alt Hacker NewsI'm still not seeing how that would solve it. These are all multiplayer games. You could intercept the network traffic before it reaches the machine and then use a separate device to give you audio or visual cues. In StarCraft, reading the network traffic with a pi and hearing "spawning 5 mutalisk" is gonna completely change the game.
You can't do anything with a locked-down computer. It can encrypt all its traffic and you can't see anything.
