Modifying DISPLAY environment variable on-the-fly

I'm wondering if there is anyway to change the DISPLAY environment variable for a process on the fly - ie: redirect the output to another X server/screen.

I ask this because I have dual display set up with my Linux box, but not using Twinview, Xinerama, etc - xorg.conf is configured to have each display as a seperate X screen. With this configuration it's not possible to drag & drop between screens, which is fine - but I'd like a way to move a process to another screen without restarting it.

Is this possible?

As far as I know, this is not possible. Part of the reason is that the characteristics of each display can be unique, and the application can adjust itself to those characteristics. The application would need to be coded specifically to allow such a relocation (which could be to another machine entirely) - in which case it would be a function of the application.
