Amazingly enough it looks like an ISO of the demo disc that was put in the Xbox 360 Kiosks is floating around on the net, and it is said to work in the Xbox 360.
Apparently they were in such a rush getting kiosks and software out to retailers they forgot to to add the normal media protection to the kiosk demo disc. Team PI has released a booting ISO of the disc with all the demos and trailers you will find on the demo kiosks. That means Call of Duty 2, Hexic, Kameo, and King Kong demos.
This might be a step towards being able to pirate full games, or atleast make backup copies of fragile DVD’s.
