[avahi] avahi-browse question

After some further troubleshooting, it looks like my power pc can send
multicast packets, but it does not receive them.  Even when I ping, the packets don't show up on the power pc network interface.

I'm guessing this is the root cause of my problem.  If multicast isn't
working correctly, perhaps it isn't too surprising that I'm seeing strange
Avahi behavior.
