That's what I thought and what I've been wondering about.  The recipient 
of the identifier needs to look it up somewhere.  99% of the endpoints 
out there today don't have global names.  Where will the identifiers be 
looked up?  Either every endpoint gets registered in something like DNS 
(and it's updated dynamically) or you depend on application-level 
intermediaries.  Either way you're depending on intermediaries and 
you've lost e2e transparency?
