With all the talk about fast user switching this is an alternate .... they could run the VM interface inside a Dashboard Widget so we can simply hit F12 and bring the VM to the foreground as a Widget while still allowing you to see native apps in the background. This would be way cool.
Stellar Idea This would be great! I am sure that it would be met with mixed reviews and opinions, but it would be a great idea. After all, I only use Windows for IE6. Now that would be a widget -- an IE6 widget!
