WikipediaP2P
I remember thinking about a similar concept a few years back. It would be good to have a p2p archive of human knowledge for end of the world scenarios.<p>The problem is Bittorrent isn't the protocol for it, it doesn't allow incremental changes. You also don't want the complete history like git, you want something that passes a diff around.<p>It would be great to have a p2p network with Wikipedia, a load of academic papers, maps and recipes, which anybody with a computer could contribute drive space to storing.
