Hi there
I tried to set up a daap server yesterday (for Apples iTunes) and I
couldn't get net/howl working from the ports. so I compiled audio/daapd
without Howl and used net/mDNSResponder as mentioned in the daapd readme.
That readme states that one should call mDNSResponder with some command
line parameters to have it announce the existence of the daap server to
the other Rendezvous-aware members of the .local network. This way has
some disadvantages: (1) You can only announce one single service, (2)
you have to start it manually.
To overcome those problems I wrote a startup script for the
mDNSResponderPosix binary. It uses the new rc.d framework (thus depends
on sysutil/rc_subr) and supports a config file that can hold any number
of services to be announced. To allow comments in the config file I had
to make a small change in the source code of mDNSResponderPosix.
I included my Config (you may want to delete the actual service
definitions and only use the samples on top), the rc.d script, and a
diff of the mDNSposix/Responder.c file in the mDNSResponder source tree
(version 62) with this email.
Maybe you want to include it in the port so that other users who want to
set up a system similar to mine can do so easily.
Cheers,
Alex
BTW: What is mdnsd (installed by the mDNSResponder port) good for? It
doesn't seem to have a man page or config file nor did I find anything
in the Apple documentation. Also it didn't want to announce my daap
server, so had to just kick it ;-)

# Entries constist of four consecutive lines as follows:
# NAME OF SERVICE
# TYPE OF SERVICE (and, if different from .local, the domain seperated by a space)

# Example (announce existence of Apache to the .my_local world):
# My Webserver
# _http._tcp. .my_local.
# This is my Apache server
