Windows 8 - Experimental Protection?

[Ncage1974]

I know its not available now on x64. Is there any info whether its coming at "some" point to windows 8 or are they road blocks your running into when trying to implement it? If so is it the problem with unsigned drivers & windows 8? If so, a possible work around would be to reboot and disable driver signature enforcement. While not the best solution it would work in a pinch

thanks...
