In the case of X11, use "xwd -root" to dump the on-screen display into a
file, or look at its source code to see how this is done under X. Or as
already suggested, use VNC if you also want to control the remote
screen.
If you just use the console, then just use GNU screen. It probably
provides already all the functions that you need (one of screen's
developers extended GNU screen a few years ago for a project that sounds
very similar to yours).
