Signaling and NAT traversal are two interesting pieces, as outlined.

It can get even more involved if you want to use peer identity and authenticate against an IDP. WebRTC is still in draft stage and browser implementations are still writing more code.

That said, it does provide a platform for interesting apps.

On a related note - I am curious how many people will use WebRTC directly or wrappers like those provided by twilio and similar.
