Transfer display of active windows remotely

[Prasad H.L.]

This is what I have in mind.

- Consider display :0 on machine 1 (m1) and display :0 on machine 2 (m2).
- Let us say, a process 'p1' running under privileges of user 'u' opens a window on :0 of m1.
- I do an 'ssh -X u at m1' in xterm on :0 of m2 and login to m1.
- Now, from that xterm window, is there any way by which I can make that window of process 'p1' appear on :0 of m2.

This kind of situation regularly occurs to me and some of my friends. We have multiple terminals at our disposal. On one terminal, I start some xterm which is, let us say, showing output of some process. I go to some other department in the institute and do an ssh to that terminal. Now, I have no way of seeing what is going on in that xterm. Well, this is a simple example, of course. 

Another example (though childish). Consider a case where I have a browser window with many tabs open in it, the window being displayed on :0 of m1. I would like to export it to :0 of m2 when I go and sit in front of m2. Before closing ssh on m2, I re-export the window back to :0 of m1 and then quit the ssh. Such a feature would be really great to have. Since, any way, currently the only dependency on the remote machine is that it should have an X server running, I believe this feature should be implementable if not already present.

With Regards,
