Well...  RFC 1035 states that 'UDP is not acceptable for zone transfers',
but it does not state that it _could_ or _would_ not happen.  As long as
it's under 512 bytes, it should work.  :-/

I'm not entirely sure it's mislabled.  You might want to bounce this over
to the snort-sigs list so Brian, Resident Rules Dictator, can have a
looksee.  :)
