OK, I'm up and running at last -- very cool.

In case it comes up again...

I'm using ZoneAlarm as a firewall, and needed to specify the receiver as a trusted local computer.

I assumed letting the audio manager pass the firewall would do it, but this being my only home-networking experience, I didn't think to specify the receiver as well.

I did have to give it an ip-range -- 169.x.x.x -- is that overkill? How can I find out what range my receiver will use?
