My understanding is that it requires a AS to evaluate the request and the
generate a ticket/token for the RS.

1) many people perceive the AS as being the cloud component and they don't
   want a cloud part.

2) but in any case, it's the form of the rules which the AS evaluates to
   make the authorization decision that I care about.  AFAIK, neither
   OAUTH2 or ACE-OAUTH standardizes that (or intends to).

If I'm wrong please correct me.
How would ACE-OAuth identify the local Sheriff?
