How about this:
1. Prgram an app that you asks the user if archive.org could store, say 1 gig of encrypted data on your hard drive? It wouldn't be mandatory, but you could help if desired. It would just sit on your hard drive. That gig of data would be changing on a regular basis. (Big data centers could offer to take in data. Hell, they could have another tax right off at the end of the year.)
2. After all the data has been distributed around the world; the data transfer would start over again, but on different computers. In a short amount of time you might have millions of computers with part of The Internet Archive sitting idle on users hard drives. The end result is the users would be worker bees; waiting for the queen to call them home. (In the end, you might have 1000 computers with the same block of data on their hard drive. Why because computers don't last forever.)
3. If we had a catastrophe, once the new Internet Archive was repaired/restored; the data lying dormant on millions of hard drives would come home to papa in a orderly manner.
4. It would remind people of the importance of preserving history. It would bring more attention to The Internet Archive. It would bring in a sence of team. Why not try it until this 592c3 gets their donations?
5. Yes--this is off the top of my head. I would need to put more thought into it.
