Can't think of ways to make it cleaner off the top > of my head, but I'm open to ideas. What about using an uml wrapper + vncserver? This would give you a complete virtual environment, and if you can make uml suspend-to-disk, you've got most of it. (I admit I never tried uml, so this is just a guess.) Off cause the network connections will still time out etc etc, but that's nothing you can do about that.
