Fantastic!  Thanks Russell!

I don't suppose there are any gotchas or caveats that I need to be aware
of, with respect to running avahi to advertise services to Macs over the
same network? I'm aware that zeroconf runs on different ports, but am
currently blissfully unaware of any potential pitfalls of doing regular
DDNS and zeroconf on the same network...

Cheers (and thanks!),

Ben.
