live copy of an X screen

Hi all,

I've been searching for a while for this but don't seem to find a 
solution. My quest is: Is it possible to get a copy of an X screen so I 
can display it somewhere else?

Suppose I have two X screens :0.0 and :0.1. Would it be possible to 
capture :0.1 and display it in a little window on :0.0? This would be 
extremely useful for running things fullscreen on a second display 
(:0.1) while controlling it from the first (:0.0) while being able to 
see the contents of the second on the first display.

I could write some capture code and get a framebuffer this way but I 
thought I would first explore if this isn't somehow built in already or 
done before?

Any thoughts/suggestions?
