Hi George,

Which AG RPMs did you use?  I'm running RHEL3 on my audio and video
machines and WinXP on my display machine.  I used the RPMs from the
University of Queensland site at


One thing to note is that the rat in those packages needs to have
the ALSA sound drivers installed (it looks for /proc/asound/version
and dies if it doesn't find it).  Once I installed the ALSA sound drivers
(and unmuted the volume!) Rat works well.  I'm using a service certificate
for both audio and video machines so that the AGServiceManager.py can
be run at boot and needed to make some changes to the /etc/init.d/agsm
script in order to get it to run properly.  I will attach my notes.

I haven't had any problems with connecting to the audio and video
machines from the display machine.

It does take me quite a while to change venues as well.
