Maybe a stupid question but - are there regulations ISPs might use against this? I know it's illegal in most places to resell your bandwidth to neighbors and I wouldn't put it past them to equate giving away with selling. I also wonder if HBO and other channels might get overzealous and shut people down for the p2p nature of it. But all that said, this is the obvious future of the web until we have a true, free, ad hoc/distributed network and on some level I can't believe it took this long to get the ball rolling..
