Thanks! I'd be curious also to hear what sort of applications you plan on building with WebRTC. My own interest lies in HTML5 web gaming and peer networks.
Another useful resource for starting with WebRTC is Sam Dutton's Simple Info site:
The example doesn't use a signaling server, you must copy and paste the ICE candidates between browsers (do not use the same browser for the example, that's cheating) and then the connection is established and the database is replicated every time you add a document.
Also, read the source, it's very very simple (since you must provide your own WebRTC DataChannels).
