The ices idea works great. the delay is between 3 and 7 seconds, and
seems to vary randomly.
A couple of things for anyone else wanting to do this:
the ices-jack in the kh svn was broken when i tried this. the tarballs
for libshout and ices at karl.mediacast1.com work well.
also, mplayer on the video machine dropped the audio signal with a "too
many frames in the buffer" error whenever the delay was adjusted to
greater than 8 seconds. I fixed this by playing the stream on the audio
machine with the -cache 32 option, and also by disabling the burst on
connect option for the icecast server.

Now is there any way to get dvd menus in mplayer? or if not, how can i
figure out which track is the movie on a rented dvd? half the time the
first track is some trailer, or a special feature, or something.

Also, is jack realy required in this situation, or could i set up a
dummy pcm channel in alsa to send the audio to from mplayer and to read
it from in ices? (asoundrc?)

one last thing, c. I noticed that mplayer natively supports the network
audio system. So you don't have to use their limeted player to take
advantage of the networkness. Not that i know from personal experience,
or anything, but that is what it looks like.

thanks,
Brian
