This is a really nice overview of the nuances of WebRTC.
If you want to try this tech at a higher level, I maintain an experimental hobby project that attempts to abstract all the complicated parts of WebRTC into a simple API. Most importantly, it obviates the need to run your own signaling server by piggybacking on various public protocols like torrent trackers or IPFS to match peers. It's well-suited for quick projects/prototypes.
