As I understand it, the display migration protocol for X requires the
application to be connected to both the "old" and the "new" displays
for a brief period before disconnecting from the old one.

I think the problem with your scenario lies in controlling where the
app reconnects to-- remember that once you kill the initial display
connection, the app has no UI.

An alternative is to start up xvncserver, which creates a virtual
display that the clients can connect to. Then, you can point one or
more VNC clients to xvncserver, and disconnect and reconnect at will.
