for bandwith reasons, i had a headless VNC X server on the box, and executed X apps locally. Then i'd also start the usual Xserver and client and run a vnc client full screen. So i had the first vnc X server showing on the screen. then on another box, i had the usual X server+client combo, and i could open a vnc client and have fast remote access and shared screen :)... vnc was much faster than remote X as it only sent input and graphics. X sends all sort of metadata that is not really that useful for most cases.
