Thanks for the help everyone. We have “upper end” Dell Optiplex 5080s for the guests (If you think that’s a bad choice, lemme know. We’re not beyond changing gear to make this work.).
So I’m thinking assign one of the AUXs on our ATEM to send video back to the guest computers via a capture device. Something like:
ATEM SDI Aux > SDI to USB capture device > Dell Optiplex 5080.
Then that’s when I’d bring it into OBS/Xsplit/etc.? And from there, Skype (or whatever we use) would see it as a webcam so guests can see whatever we send them. Audio would come in directly from Axia. Does that sound about right?

PS: Sorry for the double posts and withdrawn stuff. Apparently, I don’t know what I’m doing. I think I figured it out now.
