Compares controller input (Mouse/KB) to game data (Network) and flags - seems like a clever way to detect aimbots and other movement assist cheats.  Would be great to see this in live tournament use after all those CS:GO top players got caught.  I don't really see e-sports as legitimate in its current state and its unfortunate that we need things like this to ensure fair and honest game play.
