I'm running the same activation key of Vista Ultimate in both Boot Camp and Parallels. The way I see it, I'm running it on the same computer, and I'm not running the same copy concurrently more than once. That falls fully within the license agreement. What I *REALLY* want is Parallels 3d graphics that supports Aero. I know it's silly, but I want to be able to run DreamScene in a window.
