Not a really good fit. In general, you already *know* the hostname that
has the service - it's the host you have the NFS mount from, or the current
CXFS metadata server if you're inside the cluster. And trying to use DNS-SD
for two logically distinct DMF archives is just *looking* for trouble.

It would be a much better fit for portmapper actually (although that would
involve leaving a daemon running to answer/forward queries - probably not as
big an issue today as it was when they started coding DMF almost 25 years ago).
