The author here, I apologize for any confusion from my writing. We do use WebRTC in a server-like fashion. The browser attempts to establish a P2P connection with the host computer, and the peer negotiation is similar to if you wanted Chrome to talk to Firefox for a video call. The network of either end could both cause connectivity to fail which is when we fall back to direct WebSockets rather than a costly TURN server.
