To me its just obvious. You want to put your stuff someplace where the cops can't just kick in your front door anytime they want? Put it on an autonomous aircraft or an autonomous zeppelin/balloon/blimp whatever. They are CHEAP, they are easy to make in your mom's basement, they can do the job you want them to do be it file server or phone sniffer/cracker/whatever, and the best part is the cops can't get to them. Physically can't get there.
The world's largest and most resilient BitTorrent site plans to redefine "cloud computing" with a plan to move at least some of its servers onto unmanned drones miles above Sweden.
In a Sunday blog post, The Pirate Bay announced new "Low Orbit Server Stations" that will house the site's servers and files on unmanned, GPS-controlled, aircraft drones.
I mean, are we going to have police units running around Europe and North America shooting down glorified model airplanes all the time? Unlikely!
But even if they do try to shoot them, shooting them down with what? Stinger missiles? AAA cannon? Jet fighters? You put a drone up higher than the airline industry goes and have it stay there stationary for a couple of days on solar power, that's going to be a hell of a thing to try and stop. The cost of such an aircraft would be considerably less than the cost of the fuel for the jet that's going to go shoot it too.
It is also the answer to Barack Hussein Obama's fabulous Internet Off-Switch. Sail a few of these things over every city in the country, you've got basic text internet instantly for anybody willing to aim a TV dish at it.
Way to go Pirate Bay!
