[AG-TECH] multiple video capture machines?

I think that you should be able to do this through the Node Management
interface. This may be too sophisticated for the wizard (I have never
used it, is it different than the Node Management interface or are they
one and the same?).
You will have to run an AGServiceManager.py on each machine (Display,
Video Capture, and Video/Audio capture). You then should be able to just
add each machine to your ServiceManager list in Node Management. Add the
appropriate services: VideoConsumer on display, two VideoProducers on
VideoCapture, and two VideoProducers and an AudioService on the
Video/Audio capture computer. Save this as the default node config and
it should just work. We do this in the CoLab because we have multiple
display machines and need to run some services on specific machines in
some cases. We have multiple node configs that we load depending on the
circumstance. Works well...
