Addressing is routing is addressing.  ;-)

I'm not sure I see the connection.  Intrinsically, anycast is _not_ 
about locators.  It is about services.  If you take Bill's approach (how 
about we call it 'anymap'), then obviously, that resolves to a real 
(locator, identifier) tuple.

The actual recipients are already known.
