would there be any way to have a switcher that could be operated from 2 different places? without breaking the pastor's rather small bank? (has the tendency to not want to spend much for technical equipment)
I have one of these and love it:
http://www.networktechinc.com/vmtx.html 8 inputs x 4 outputs. Handles our front of house projectors, the back wall projector for the stage display as well as our lobby screens. I wrote up how our system is set up and how I use it
here. It has a web interface so any device on your network can control it. They make DVI versions too. For HDMI I'm considering the Just Add Power devices - but they are in a different price range which is why I am still considering them
The only control we use on the projectors is the power on/off - everything else is done on our matrix switch.
