ok, since there's little in the way of useful responses, here are some results i've found since asking. first, there's a draft standard for arranging p2p connections with tcp hole punching (STUNT or STUN for TCP) - http://tools.ietf.org/html/draft-ietf-mmusic-ice-tcp-16 http://tools.ietf.org/html/draft-ietf-mmusic-ice-tcp-16 second, there's a draft standard for sip over websockets (sip is a protocol used to arrange a connection between two peers) - http://tools.ietf.org/html/draft-ibc-sipcore-sip-websocket-00 http://tools.ietf.org/html/draft-ibc-sipcore-sip-websocket-0... these almost overlap, but there's an annoying gap, which is that i can still find no way to connect websockets to tcp. so you could use sip to negotiate a circuit, and you could use ice to close the circuit using tcp, but not (afaict) with websockets. furthermore, because of how websockets seems to be implemented (it's kind of multiplexed in to http, as far as i can tell) it seems like it would be hard to close this gap.
