Peter, this is the address vs. routing issue again.  I suspect we might
both agree that pure bang routes are unambiguous, at least with respect
to syntactic parsing precedence.  The use of domain names in bang paths
also provides an advantage with respect to the syntactic determination
of unambiguous routes in an environment in which there are duplicate
host names.  This ambiguity can be resolved semantically with an edge
database, or syntactically with domain names.  You like edge databases
and semantic disambiguation.  I like domain names.

I am not aware of any sites which cannot handle the cbosgd!cbosgd.ATT.UUCP!...
stuff.

Of course, one of the main problems with mail in general is the lack of
a decent user interface.  Some deficiencies in the user interface are simply
coming to the surface in the issue of addresses vs. routes.
