This is pretty tricky, because the solution would probably imply that 
the OP is able to generate OAuth credentials for the SP. Presumably both 
the SP and the OP would need to agree on how to provision and verify 
consumer keys (and consumer secrets) and somehow the user would need a 
way to revoke an OAuth credential after it's been issued.

Well then you'd need to send the identifier to the RP, and you'd also 
need a way for the RP to determine if the OAuth Service Provider is 
authoritative for that identifier. These problems have already been 
solved by OpenID.

I don't think the non-hybrid UX is all that bad. We have that today with 
Flickr in which Flickr is the SP, but Yahoo is the OP.
