NOTE: I don't think your use of directed identity here is what Kim  
Cameron meant by directed identity.
Since each requesting entity has the same identifier, they all know  
it is the same user, and could collaborate and share identity data.  
In order for there to be unidirectional identity, each requesting  
entity would need to be given a different identifier.
