Just pointing out that P2P backup is a well understood problem (in industry and academia) and they should probably partner with people who do this stuff serious

  One of the more interesting design requirements here is that the system should work even when the distributed content is _not_ encrypted. If I join this backup effort, and a meteor takes out all of SF (and thus the Internet Archive), and their off-site backups fail, and the aftermath is preventing me from accessing the internet, then that 1TB of data that I had downloaded is all still usable to me. It's not some giant encrypted blob, it's a bunch of zip files (or similar) containing images, sound, video, web pages, and other types of files that I can, in principle, already use. (Maybe I can't do anything much with that Apple II disk image, but I can at least identify it.) Git annex and BitTorrent would both work with that requirement, and most of the commercial, proprietary solutions cannot; their clients wouldn't use them if that data wasn't private.
