Well, if you want to run a desktop app on RT, you have to contact Microsoft and get a license from them to do so, as only applications signed by Microsoft (and it appears, meeting a few other criteria as well) will run in the desktop on RT. As a hacker, I'm not sure what you'd need to do to get a non-signed app to run from any location, but especially protected locations. You can bet Microsoft isn't going to be publishing that info
