Software :: X Forward Of An Existing Process?

I know I've done this before but I haven't had the need in awhile and it escapes me what I did. Basically, I have a box with a ssh service with X11 Forward on. I can connect, initiate a process on the remote box, and see the program as if on the local one - all good.What I would like to do, though, is say I fire up a process - lets say a cdburn from a gui and not a cli on the ssh service box. Then I go to a remote box and ssh into the one burning the cd. I'd like to pull what is being displayed on the remote box to the local box so that I can see the progress - without looking at text log files - I want the actual display.This is just a simple example of more I want to do, so getting the actual display as an interactive display is critical. I seem to remember something about finding the process id and connecting to that, but again its been years and I forget.The other option would be to forward the entire screen, sort of how windows does remote desktop, but I'd prefer on a process by process basis if possible.
