PS2 Games to be run on Xbox 360?

Knowing that emulator configuration updates can be downloaded and burned to a CD means that the world will be able to pull apart this file and analyse it.  This also means that possible PS2 emulator files could be created allowing PS2 games to be run on the Xbox 360.  And why stop there when you could create the same thing for the Sega Dreamcast or whatever.  Here is the snipet that details the process:

 

"you can get the latest software updates from Xbox Live, burn a CD from xbox.com or sign up on Xbox.com for a CD that can be delivered to your home at a nominal shipping and handling fee. Once you get the CD, put it in your Xbox 360 and you're ready to go."
