That might actually be harder than it sounds. Because there's a 
connection between the application and the X server, it's hard to just 
reroute that connection to the other server.
This'd involve some extension on Xlib's side too. To move just any 
application you'd have to do this automatically in Xlib without the 
application having any control over it. (older applications are not 
aware of the extension and we still want to move those)
There'd have to be some extension on the server side too ofcourse. I'm 
guessing there's a seperate application, like the window manager, that 
tells the application to move (actually talking to the extension on the 
X server) and the server then telling the Xlib part of that application 
that's about to move to disconnect and reconnect to another address.
Three problems I can think of right now:
- Where are we getting the addresses from? The window manager (in this 
case) would have to know what other X servers there are and where.
- Would we allow the application itself to control (part) of this? Some 
Xlib functions for it? I have no idea. The way I explained it above it's 
handled fully in Xlib.
- How are we going to redraw the contents on the other X server? Is it 
possible to just send an expose event for the entire window? Or would we 
have to resend the current state of the window? There's two ways to do 
the latter, entirely on Xlib's side or the X server extension contacts 
the other server (in which case the other server needs an extension for 
it too).

If there's an easier way, again, feel free to correct me. ;)
