Re: [rtcweb] Use Case draft

Stefan,

This usecase add its own requirements from identity perspective as 
I mentioned earlier. 

WebRTC MUST allow "Anonymous" users secure session for call center
usecase. "Anonymous" User may be agent in the call center side or 
customer who does not require Identity to start the session.

Thanks
Partha
