Thanks for your comments.
Yes, we can implement the federation between SPs through using the same signaling protocol (e.g. SIP) or deploying a gateway.

But what I concern is how to compatible with the existing various user id from different SPs. For example, if Google provides WebRTC client, then the users should be able to login using their Gmail address. In the same way, Facebook support the users using FacebookId. So the format of identification may be number, string or email and so on.

The problem is how to handle addressing users of different SPs. Should it be standardized to a unified WebRTC URI?

SIP is an established standard to interoperate domains. We at developed a video/audio bridging service for WebRTC. Although it uses JS/JSON signaling for web based clients. Our server could very well federate with any other service using SIP. What does need to be discussed on app to app basis is what kind of federation you are looking for?
In case of bridging service we could merge calls from both servers or redirect all the calls to the host service.

As I understand it, it’s not just a problem of identities.  WebRTC does not define the signaling protocol, but leaves it  up to the application.  If two users download their applications/JavaScript from the same site, it won’t be a problem, because the same application is handling both ends of the call.  But if one user is on site A while the other is on site B, there is no guarantee that either site’s application will understand the signaling from the other.

Unless websites agree to use something standard such as SIP/Jingle for federation (inter website/domain communication).
