And since the service can be configured to run on any port, what kind

If I use shortport.port_or_service(31337, "BackOrifice","udp"), it
won't be able to run on any port, and this script will be the main one
to identify a BackOrifice service running on any port. The probe is no
good, because it only works with default encryption (initial seed
31337) on port 31337.

There are version scripts which run on (almost) any open port. See
skypev2-version.nse portrule. However, as I understand it, the
BackOrifice service looks filtered unless you can authenticate
properly with it. If we were to run backorifice-brute against all
unfiltered UDP ports... that would take a while ;). I think for this
we need a script argument where the user suggests a port list to run
against. Something like: --script-arg 'backorifice-brute.ports=31338'
or --script-arg 'backorifice-brute.ports=1-65536'.
