Well, in your other post you didn’t specifically say your objection was that one couldn’t run a Mac OS, but that’s not a limitation of Windows per se. Mac OS’s are not licensed to run in a VM, and I think the VM software vendors don’t want to anger Apple by allowing you to do it. If VMware, etc, would write it, I believe it wouldn’t be any harder than installing various flavors of Linux, OS/2, BSD, UNIX, etc., all of which can be done.
