There are many p2p networks for streaming content - they seem to be popular in Asia for watching English and European football, and I think many of these existed prior to 2007.

I'm sure there's a mountain of other prior art covering the concept. It isn't novel to anybody with half a brain. I was streaming audio in the 90s and clearly remember thinking about a p2p network then, because of the expense and legal threats I was receiving. All I wanted to do was enable football fans living abroad to listen to the local radio station on match days.. I thought I was doing the BBC a favour by extending their broadcast range! Yeah, I was just a naive kid. :)
