Well, my concerns were mostly that I'd have trouble with the Windows
variants as guest OS's.  I'm reasonably confident that I can get Debian
going as my host OS with little difficulty, but the Windows guest OS
question is nagging at me.  I don't really care what version of Windows,
(e.g., XP or 2003 Server would be fine), as long as I can get one of
them to work without too much jumping through hoops.  I'm all for the
pedagogical experience, but if getting those platforms to run is going
to be unreasonably difficult and require constant bug-fixing, I'd like
to know that beforehand so I can make accurate estimates for the
upcoming project.  Again, any advice the list can provide is welcome
and appreciated.  Thanks!


Best Regards,

Ryan
