The definition of a WebID shouldn't be based on implementation details 
re. style of HTTP URI. Secondly, I already gave you an example of proxy 
URIs based on 303 redirection. The ability to produce 5-Star Linked Data 
for specific purposes without waiting for Facebook. Example, how we 
enable any Facebook user acquire a WebID that resolves to a profile 
graph that's usable with the WebID over TLS protocol re. authentication.
