Oh, absolutely. We went round several circles arguing this recently, and
concluded that there was nothing we could do to improve matters. We
*don't* have a list of local domains - a global domain takes precedence.
Only if there is no global domain do we try for local abbreviations.

As soon as we realized, we stopped issuing internal domains consisting
of only two letters, to minimize the risk. (The existing two letter ones
to back to the days before we were connected to the Internet.)
