Hi Guys

I'm interested in p2p from a technicl aspect, but I was wondering is there any tools or pages that compare p2p solutions, indicate which flavours are growing, whihc are on the wane, etc.? IT strikes me that the biggest vunerability for p2p solutions is simply lack of support and downloads. Are there any companies looking to commercialise p2p networks, thus maintaining a core network?
