Yes, that would solve my concern about wasted resource of having 
multiple copies of the same OS when all I want to do is run multiple apps.

In my case, I don't mind waiting 6 months for the virtualisation-enabled 
AMD or Intel processors to be available.

BTW, in my case I intend using Windows XP embedded which, amongst other 
things, will allow me to reduce the footprint of the Windows OS. I am 
assuming that there shouldn't be any problems with that with the current 
plans for Xen supporting Windows (?).
