Twinview over network
I have 3 machines on a LAN using Redhat 4 and I need to use one as a pannel to show the others' display, that is, one machine has a big tv connected on it (lets call it server), and I need to see on the tv what the users of the other two machines (clients) are doing. The clients must display image on their own monitors, so it must be a clone image. They also control the programs, so it's not a regular X session where I start the display on other machine.
Is there a way to do this with X?
Are there programs to do this? Should I use VNC?
