I have some experience in this from developing https://p2p.chat https://p2p.chat a while back. As others have mentioned, building a simple project is fairly simple.

Adjusting audio/video constraints to ensure that you get optimal media streams is quite difficult, also. Nevermind dynamically tweaking them!
