Well, IIRC portmap just does mappings from RPM IDs to port numbers for a
particular machine - it doesnt know about protocols, and it doesnt work on
the subnet level.
You could do some two layer thing where you use portmap to discover the
sevice discovery service, you you still need to define the 2ndry protocol.
With zeroconf you can ask for all services running on _udp._osc (or
_tcp._osc, etc.) and get them back, which a short description and/or a bit
of metadata. Much more useful.
Also (in the realm of hearsay here) portmap has a strong reputation
for general bugginess and ickyness.
