Well, for what concerns the part I focused on (the canvas part) there should not be any performance issue with p2p.

For WebRTC p2p video streaming in general, it seems promising. At the moment, though, there's little to no browser support and getting a full system (there's also a server involved, to initiate the connections) is not automated or abstracted yet.
