Re: Interesting ToS
although probably not impossible with clever enough error-correction code
It doesn't really need to be clever. With infinite storage you can include as much redundancy in your data as you like. The only penalty is the amount of time it takes to upload to / download from Amazon's servers.
You could for example backup your entire pirated movie collection by uploading a series of 800*100 pixel jpegs where every 100 pixels on the x axis represents a new bit (black-ish being 0 and white-ish being 1). Amazon could compress the hell out the files and they'd still be readable.
