I wonder if torrent/p2p would be a viable business model for Netflix. Think about it : they have a massive install base inside comcast where they can run programs and on most such programs they can run code, and store data.
P2P isn't a good architecture for something like that. You pull data from a leaf node, through the core network, back to another leaf node, traversing the relatively slow last mile coax part of the network twice. Meanwhile, a relatively small number of movies and shows will dominate the demand, which Comcast can easily cache near the edges of its network. There is a reason Netflix is vying to get equipment in those spots.
Solution seems obvious.
