If it is the same URL for all users, then it is not directed  
identity. What you have done is generated a "random" URL for them to  
use so that the Yahoo OpenID is not linked to their Yahoo account  
(unlike the AOL OpenIDs).

Directed identity is what Sxipper does where a different URL is  
provided for each RP. Cardspace follows a similar pattern with the  
self managed cards.

This does not need to be added to the specification as it was  
anticipated and the management is out of band of the protocol.
