P2P networks everywhere

A lot of people has said already that WebRTC and Peer-2-Peer comunications in the browser would be the next Internet revolution ("Internet 3.0", they call it), but I wouldn't suspect that this would start so soon: the next 7th April will be released PeerKit, the first WebRTC P2P enabled application (besides my P2P filesharing application :-P ), this case oriented as a distributed, zero cost Content Delivery Network. I don't know how effective or speed it would be (search a peer with the data, delegate the request...) and there's the problem of using the client connections to distribute the content (and with mobile phones connections this would be a serious problem), but don't doubt that if it works the server costs will drop abruptly world-wide... :-D
