Danny,

Response to Dave did express #1 is UI atop API. But then I remembered a 
wonderful little thing called FOAF+SSL that binds a Person Entity URI to 
an X.509 Cert. that is then exported to a Browser and usable across the 
Web as a WebID. This very WebID is the conduit to the profile of the 
person who is issuing the query. So yet again, we have a real world 
problem and the dexterity of HTTP  URIs to the rescue :-)
