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.

Subject: [rtcweb] WebRTC service between SPs

Hi all,
I have followed RTCWeb discussion for some time.
As far as I know, any website can conveniently integrate WebRTC service, particularly social networking websites. It can easily be predicted that many service providers (SPs), especially social networking SPs will release their WebRTC services in the near future. But I am wondering how the users under different SPs can communicate using WebRTC client. Each SP offers different user identity in different domain. Although some mechanisms can support to login multiple websites using a uniform account, such as Persona ID, OpenID or OAuth, they have different Idps, and not all websites apply the same mechanism.
I am not sure whether it is a problem. Thanks for your any comments.
