The biggest problem is likely to be learning enough about how it works
to boot something BESIDES an imaged install. Winsux tends to provide
you with a GUI and then keep you out of and away from the actual tools
being used, so if it ain't on the menu it doesn't exist.
My own PERSONAL opinion is that it would be a damn sight easier to just
put a server node into your minicluster to make it self contained. If
you're using OPM, just integrate a cheap laptop with the thing.
