I've thought the same thing. OpenID-OAuth Hybrid is exactly about  
that separation, replacing the old issuing dance with a new one.  
Verification needs to stay the same.

At that point, the only difference between OAuth and SAML or Kerberos  
is that there is no standard way to present credentials to  
Authorization endpoint. I assume this will be handled by an extension  
in the near future, allowing one consumer to present its credentials  
to authorize another consumer's token. I think someone might be  
calling it transferable tokens in some extension?

I've also hoped the token would begin to take a more capability-like  
role. All that would be needed would be to explicitly mention the  
resources the token grants access to, and the rights it provides.
