Actually this is entirely achievable right now, with very little code. You can use WebRTC in chrome / firefox, which implements all the nasty details of peer-to-peer communication for you (and uses TLS-esque security). All you need is a STUN / TURN server and something to do the initial handshake and you're off to the races. I've not gotten around too it, but someone should setup a webserver that speaks the protocol (perhaps with this: https://code.google.com/p/libjingle/ https://code.google.com/p/libjingle/) then you serve your site as a static HTML file on AWS or similar, spin up WebRTC, and then communicate with your server that way. Now you can serve a whole website sitting behind a firewall.
