https://www.maidsafe.net/ I like the idea of this. You download their software and dictate how much space you are willing to give. Then the network distributes the files needed for it's sites and data over the network like a bit torrent p2p network. The beauty is you don't need a web server as it utilises the computer power of people using the internet. Which is a lot more efficient I'd imagine. It's been 10 years in the making and think I'll have a play around with it later.
