It does seem to be possible to run programs on another computer (a sshd server) using ssh -X (and view the windows on the clinet computer).
Now ssh "tunnels" the X communications, so it sets DISPLAY to something like localhost:10.0, and redirects everything sent to the relevant port on the server computer to the X server on the client. Therefore Wine must be looking at the DISPLAY environment variable, but not allow you to connect to a different computer.
Perhaps this is something that is now disabled by default but can be enabled in a config file?
