I used PeerJS for a project, http://subsect.net , that has been running for a few years. I have run my own PeerServer on Heroku all of that time without incident. I have tested connectivity over WebRTC from many places around the world and have never had a problem other than from the lobbies of some banks as it seems they generally block IP traffic.
WebRTC is a transitional technology and I look forward to the day blocks of IPv6 addresses are granted free to all people at birth and fixed addresses are supported on all devices.
