Windows Server on a USB Stick

[Vast]

I've got a 16 Gig USB stick. I'm wondering how hard it would be to setup a functional windows emulator on it. I was thinking mainly for testing purposes (localhost only), with a mini-login. Any input on the idea?

If it gets mapped to a drive letter and you can setup a normal directory structure on it should work just fine. Not sure how fast they are but they should be at least as fast as a real hard drive.
