Microsoft just released the Company Portal Windows App which is basically a Windows Intune Client, which allows you to deploy Apps on your Windows Intune managed devices.
App Description:
Note: This app requires your company to have an active Windows Intune subscription and to have provided you with an organizational ID to sign in.
I posted a quick walkthrough on what it looks like on a Surface RT:

And now that SP1 has been released for SCCM 2012 you can use it there as well (in tandem with Intune.)
