Internet Based Remote Control
Internet based remote control with options such as file transfer and reboot. This could be accomplished using a reverse connection from a client to a new site role hosted in the DMZ.
Try this out over CMG in #SCCM TP 1906

I'm not trying to knock this idea at all, but wanted to mention that this can be accomplished using DirectAccess. If you don't want or need the users to have corporate connectivity remotely, DA can be configured for Manage-Out only, so that you have full management access without giving them access to corporate resources.
