Man, it seems as if the only thing missing is a data bank where you can drop off your hard drive and the bank will store it for you and even lend out free space to others at an interest. Yay virtual currency.
It's not quite what you describe, but bank vaults are actually quite cheap. The computer expert firm I work for has two large vaults (something like 8 cu. ft. each) at a KeyBank where we store scores of hard drives. We make a trip every Friday to rotate our set of backup RAIDs. It's a very simple, straightforward process, and I think our cost is something like $40/month for both vaults. You could probably get a vault big enough for a 2 TB external drive for something like $5-10/month.
