How to mirror display of widows 8 to tablet and tv at the same time.

[gaidin43]

So with the release of windows 8 and the free media center I am planning on trying it out on my HTPC. However, I am trying to figure out a way I can use a kindle fire HD or a google nexus 7 as my remote by mirroring the desktop and the metro UI to both the TV and the tablet at the same time. Does anyone know how to get this to work? If I log in remotely using Remote Desktop it locks the main display screen (the TV).
