Anant Narayanan has been using a mechanism like this as an example in WebRTC spec discussions - basically a distributed-hash signaling layer (if you will, a self-healing incomplete mesh used to connect nodes for signaling a webrtc call) - and the distributed hash mesh could be a mesh of WebRTC connections with datachannels (no media).

The effect might be an encrypted, hard-to-block (barring deep packet inspection at all the edges or shutting off all access) communication tool. Identity verification would be important for some uses, but not for others.

OOB negotiation via any other channel can be used to join a network (see the article on serverless WebRTC)
