Does the Windows version of the Aquarium run on a Mac running Windows?

I think this is going to work in Apple's favor, as people can now justify buying a Mac because it will run Mac or Windows programs. And I think the Mac interface will appeal to a lot of people who have never even considered it. There are definitely some bugaboos that drive me nuts about the Mac interface but I'm sure Vista will be a lot like that too.
