you should need only a connection between the two X over tcp/ip inside usb..
but as I understand, the refresh is implemented on the gtk+ libraries, so a program running on your computer but displayed on the DR screen will be using computer's gtk+ libs, and computer's X client (in fact, the program, which is linked to computer's gtk+ and X lib) will send X bitmaps/pixmaps to DR's X server that will update the screen.
Anyway, try and share the results ;-)
