Another real life example as to why cloud computing is not seen by many as a viable solution.
i disagree. if anything, virtualized hardware will make it harder to track these things down and keep these sites offline.
think about it: a rack of 6 physical servers is actually running 120-300 rented virtual servers. which of those 6 is actually running the site that you have a problem with? do you confiscate all 6 and knock 119-299 other servers offline while you figure out what the problem is? do you just confiscate the 1 server and take 19-49 others with it?
do you just have the vendor take the 1 virtual server offline and email the VHD/VDI files? this is where block crypto comes into play on the virtual server side.
add to that a little forethought, say a non-US registered domain name for your questionable site (all of my favorite trackers are going to .me, .it, or .ph), good backups, and a second or third server in a different country with a different vendor, and you see the problem that seizing physical hardware presents.

It seems to me the process of "engineering" , and packaging the micro solids and the chemical & power requirements to do so could not be called remotely sustainable..
repraps don't use cartridges. they use loops of ABS filament and a gear to push it through a heated extruder called a thermister in a process similar to the frosting bags you use to decorate cakes.
ponoko is more of a marketplace for 3d things, and a lot of those things are laser cut and not always 3d printed. my favorite ponoko design is the ponoko reprap: http://reprap.org/wiki/PonokoRepRap
The ABS thread cartridges the printers use work out to costing about $5 per cubic inch of material or dissolvable support material.
yeah, and intricate parts can also take several hours to print. oh, and with the desktop size of the makerbot or the mendel, you are limited to parts that are less than a cubic foot in size. also the ABS that repraps and makerbots use (it looks like weed eater cord) is about $10 per pound.
but even a 12 hour wait for a tiny, goopy gear made from what is basically melted lego is vastly cheaper and easier than waiting for 1000 parts to be injection molded and shipped from china, especially if you aren't done prototyping.
The mechanical properties of a 3d-printed part are often not very good because of the striated pattern caused by the rastering motion of the printer head. This means that parts can't take impacts, high stresses, or high rotational speeds. The material is also prone to material creep.
also true, but the purpose of a 3'd printer isn't always to make production parts, but to make one-off prototypes.
once your part is designed you can move up to a different (even slower, even more expensive) one-off prototyping process, like sand casting or CNC milling so you can make your part from aluminum or another metal, or laser cut it from a sheet of plastic, wood or metal.
3d printing is just one part of the desktop rapid prototyping stack. desktop sized CNCs and desktop laser cutters are also out there.
runs of a million widgets in a fully automated mega-factory will be always be cheaper on a per widget basis, but that's a very 20th century way to approach things.
the future is really uncertain from a supply chain standpoint. fuel pricing and natural disasters mean that making millions of widgets in one place and shipping them all over the globe could be a risky and/or expensive proposition.
look at how earthquakes in asia have affected the markets for electronics over the years.
As for the mechanical properties of printed parts, RepRap models Darwin and Mendel can print the majority of the non-threaded parts to make another Darwin or Mendel, and I'm not aware of any reports of mechanical failure of these printed printer parts.
the only reprap parts you can print are the joints. most of the structure is metal thread rod, and the actual work is done with micro-controllers, stepper motors, and stepper motor driver boards, all of which you can't print.
i used to work with a guy that ran a bootleg DVD operation to supplement his income in the 2002-2003 recession. he had a decent network of people who bought from him to sell, so he was mostly into distribution.
the myth behind this is similar to the myth about drug dealers. it's true that a small number of people make a lot of money, but for 99% of the people involved, it's a low paying grind, like any other job in a highly competitive field. most of the dudes that sell drugs still live with their moms, and my friend didn't do much better.
at first i thought it was easy money: boxes of discs would go out and dudes would hand him wads of cash since he was more of a distributor. but there so many nights where he would up til all hours when something new hit the scene and he needed to get large numbers burned in a short period of time.
and then there were the material costs: buying thousands of blank DVDs, running 4 computers to duplicate them all in batches of 8, and the printing of the covers. he'd burn through printer ink like it was going out of style, and even filling the cartridges himself was expensive, not to mention wearing out print heads.
i guess it's different if you have mob money to use as start up capital for a large-scale operation, but for an independent it's a lot of work and expense for not a lot of return.
The same companies who are endlessly whining about the money they are losing to file sharing... very specifically and deliberately not paying money to people who by their own rules,they acknowledge they owe money to.
the thing we fear most is often the thing we see in the mirror, so it stands to reason that a company that has made its fortune by exploiting the works of others would fight to the death to stop what it believes to be the same thing.

in case you haven't noticed, ax murder is this country's only growth industry, providing thousands of jobs for unemployed americans. it's pinkos like you that are destroying this once great nation.

The idea of charging extra for "services" was a good marketing idea in the past (charge what people are willing to pay), but I think as more and more people get a standard connection you will see a shift from viewing each service separately (voice, TV, internet) to instead viewing it only as a connection.
but... but... then cable and TV companies will have to compete!
and mobile carriers will be able to provide services in markets where they are not the incumbent local carrier!
competition leads to price wars, price wars lead to consumer savings, consumer savings leads to... THE DARK SIDE!
no thank you, i'll stick with the current monopoly system where we get nothing and pay dearly for the privilege.
Surely by now all the cloud providers have been served with NSLs compelling them to turn over all data and all passwords. So it's a good bet that anything stored there is already in the hands of the government.
strong crypto also works in the cloud. your networked data drop (dropbox, amazon s3, etc.) can store files up to a given size, so i keep a couple of truecrypt volumes stored online. there are limits to file size of course. for example, DB has a limit of 300 meg for individual files.
What happens if you have an encrypted drive and refuse to give your password to border patrol?
Does anyone know?
it happened to a friend of mine. she was pulled out of line and asked to boot her laptop, which was encrypted, and she refused to give the key. they took her laptop for 15 minutes and gave it back without a word.
her suspicion was that someone installed a hardware keylogger on it, but i doubt it, given that they only had it for 15 minutes and the disparity of keyboard connectors inside of laptops. i could be wrong, but keeping a store of loggers onsite at every major airport seems like a logistical nightmare.
i suggested she plug it in to a private network segment with a bunch of monitoring tools as a research project, but she declined.
i hope my laptop gets similar treatment when i travel to defcon this year specifically so i can research it.
