Yes, and it's tricky to make a smooth UX out of it in a web browser setting but the technology is absolutely there. IIRC we managed to make it server-less (in the true sense) apart from the need of a Namecoin gateway. Typically you would use a signalling server coupled with STUN/TURN to discover peers and establish WebRTC connections/routes but it's not required. You could take a look at Rymd above, IIRC the principles are described in the paper. Here's also a minimal PoC that I found by a quick duck: https://github.com/svarunan/serverless-webrtc https://github.com/svarunan/serverless-webrtc Once you have a connection to someone in the network you're in the domain for traditional P2P solutions and protocols.
