yup, those are exactly the customers i was told about.  (see above.)  however,
there's still a way to filter-list the various interfaces -- it's just harder
than letting the routing table imply your filter-list for you.  also however,
if these were the only customers who weren't made to follow BCP38, there would
not be a global BCP38-related problem right now.  or, as i said before:
