Well, strictly speaking this answers my question, but it raises another. I've heard that some complex applications don't work in the Parallels environment, which is why I was thinking of Bootcamp. (A friend of mine tried it, and ran into problems playing his voice recognition software and also connected to a VPN. Come to think of it, he'd probably sell me his version of Parallels cheap. He bought it several months ago (summer 2006), so I wonder if they've improved the product since then.
It was very helpful to find that Parallels at least allows other versions of Windows.
