while I agree time stamps are beyond the scope of uniqueness issue, 
adding an integer index does, in my opinion, deal with
the uniqueness issue directly.  It simplifies the provision of a 
globally unique id for each message without requiring a separate
globally unique URI to be cast for each message.
