Anyway, if you intend to show on the DR screen apps running on you PC expect some problems with screen refreshes, as those programs are not using the DR special libraries.
You should need to compile X server or VNC viewer for the DR and include code to handle refresh calls properly.
but if I remeber well.. X is already running on the DR, try "top" to check..
you should need only a connection between the two X over tcp/ip inside usb..
