It might be possible - but I'm not entirely sure about it waking on a mouse movement. You'd have to set a windows hook that is in a seperate dll to respond to WM_MOUSEMOVE messages then force the application to terminate.

But the problem with it is that it is a hook and I don't think Valve Anticheat likes windows hooks either.

Or - you could write a BSP renderer yourself and try to mimick the game and bots as much as possible - but probably not the best way to go due to the time required.
