Migration of windows between displays

Gtk has an API function gtk_window_set_screen() that lets you move a
window from one screen/display to another. This is easily demonstrated
by the gtk-demo applications "Change Display" example. I've written a
patch against gtk that listens for a _GTK_CHANGE_DISPLAY xproperty
notification and when recieved calls the gtk function mentioned above to
move the windows display. This provides a foundation for more
interesting applications that can be written, such as providing
migration of user sessions between computers, "detaching" applications
by moving them onto an Xvnc server, making x2x style programs more
versitile, "dragging" windows between non-xinerama multihead displays etc.
It's been suggested that I post here to discuss coming up with a common
specification so that other toolkits can provide the same
functionality. Also it was suggested that instead of using property
notification I use a ClientMessage to trigger the movement instead.
The bugzilla entry is available here:
What are peoples comments on this idea?
: I'm kinda new to gnome/x11 coding, my humblest apologies in advance
for any mistakes I might make.
