Hi Sergey,

The idea of the audience was to provide a way for the client to indicate the 
resource server it wants to talk to explicitly rather than overloading the 
scope field. We certainly need that capability for the MAC token work.

The audience information is provided when the client interacts with the AS.

Ciao
Hannes

ly with what we have already in the dynamic client registration document (a=

 the WG document, namely=20
 - Use Case #1: Open Registration (Appendix B.1)
 - Use Case #2: Protected Registration (Appendix B.2)

Then, we could talk about some more sophisticated use cases where informati=

This could be bound up in the client registration process since oauth clients 
don't authorize for random "targets".

That's certainly true although the referenced document did not talk
about the registration phase but rather about the time when the client
talks to the authorization server to obtain an access token.

Maybe UMA has provided a story for this already...

I think binding audience at registration time is to limiting as we see audience 
being on a per token request level and also see the audience being part of the 
restrictions for "act as" or "on behalf of" support

Yes.  The trade off is that each client_id becomes associated with a target.
