Are you using the "sugar-emulator" command?  I believe this command runs
sugar inside a Xephyr box, which creates a  complete new virtual X server.
 This X server runs on the "client"-side, i.e. your Lenny box, with its
own window manager, in this case Matchbox. Your "server"-side X server
never interacts with Sugar directly.

This approach should also work with coLinux.  However, it has significant
overhead (running multiple X servers will do that), and I'm not sure that
it would allow the user to run in full-screen mode (as Sugar is designed
to run).  Ideally, the user would be able to resize the Sugar window as
they please, including switching to and from full-screen.  I know that
VMWare Player supports this; I haven't tested anything else.

I presume that we can package up the emulator as just some .exe on a USB
stick, to be run without needing installation.
