Is it possible in X to switch display for a client/window?
Say I want to show a co-worker something I have in a xterm window, I
would then like to be able to tell that window to start using his
display instead, he can take a look at it and then give me the window
back. Is this at all possible, and if so how do I do it? Does the client
need special code for this or can a window manager handle it?
I'm quite a novice on X so if this question is silly/frequently
asked/dumb or in any other way an annoying waste of bandwidth, please
reply by mail :-)

The client has to do this. The X protocol does not allow windows to be moved from one display to another or even from one screen to another of the same display. You could write a client that copied an image from one display to another, but, of course, only the original would be interactive. Ken Lee DEC Western Software Laboratory, Palo Alto, Calif.

This is actually a quite reasonable question. The answer is that the client needs special code to close the current display and reopen on a different display. A well-designed toolkit might include this capability, though I know of only one that does, just now: X11 Viewers for Cedar. GNU Emacs used to have code to do this, and still might.
