I hope this doesn't mean you're using a command called xhost to "solve
your problem!" :-) xhost is a huge security hole, FYI. If this

Thanks for all your help. I have managed to get the remote app
working. It seems that my problem is a X11 forwarding option on the
SSH client. By switching that off and exporting the display to
localhost I can get the remote app to run even when the SSH connection
is closed. Previously, with the X11 forwarding option enabled, the SSH
server will try to establish a connection with my local machine and
thus when the SSH connection closes, so does the remote app.
