Do you have a reference implementation of using WebRTC as a networking layer? As far as I've researched, I've not seen anything which would enable reliable NAT traversal which wouldn't also make the network traffic trivially identifiable. STUN works only for certain types of NAT and requires servers which aren't behind NAT. TURN is an external proxy, so can easily be identified by monitors of the network. The concept of Orchid seems nice but the actual implementation seems very hand-wavy.
