Another solution could be to make one of the names a CNAME pointing to the other name.
-or- Just use one generic name for both services. rather than the two "service" names. Although in all honesty, I see nothing wrong with a lookup returning two answers (in a single response packet) for the one reverse query. BIND certainly is not confused. I guess it confuses people? I've written various scripts to do various DNS checks and have always made (programmed for) this assumption - that there may be more than one answer and there may also be CNAMEs involved. If other software is confused - then perhaps it is badly written? Some people do though, I believe, go overboard...
