Windows Vista can now be virtualized

I noticed from eWeek late yesterday that Microsoft has announced that all Windows Vista editions (SKUs) can now be virtualized. The new end-user license agreement (EULA) now states:

"...instead of using the software directly on the licensed device, you may install and use the software within only one virtual (or otherwise emulated) hardware system on the licensed device."

Of course, you still need to have a valid/legal license to be able to virtualize in the first place. For software developers, it would be great if some of the high-end Vista OEM versions (that comes with a PC) could be virtualized in a single additional virtual machine for testing purposes.
