> With a P2P system, you can't just send someone a link to something you found — you either expect them to have a client for the service, or use a web proxy That's not a property of P2P, it's a property of anything that's not built into browsers. That is, either the protocol is built into browsers and the browser is the client, or else it is not built into browsers and something else is the client. Modern browsers already support P2P through RTCPeerConnection. In the future there may be even more general P2P capabilities built into browsers. What you're talking about is at most a limitation of current browsers, not of P2P.
