How does this cope with the case where the NAT hole-punching fails and both WebRTC clients are unable to accept an incoming connection? A TURN relay seems like it would get blocked. Edit: I should have just read the documentation [1]. It relies on the STUN/TURN servers being public and commonly used so that blocking them will break many other applications. Unfortunately, I don't know if the regimes where this is needed will care about that.
