WebRTC is not a silver bullet, it mainly standardizes the profile for enabling interoperable media (via SRTP, SDP,...) and an API to control it from JS. The signaling is open, so it is mainly up to the developer to decide the topology they want to enable: p2p, mesh, centralized MCU, hub-and-spoke, overlays, etc. However, in many cases you'd have to use a TURN server to communicate from within very restrictive firewalls. This turn server could possibly run by anyone, including you. Just need to call the appropriate API with your own TURN server. I run restund (a open source turn server) on an amazon instance and route my packets via that (I also remove all other ICE candidates and just keep the TURN).
