I use Linux, but cheating in multiplayer competitive games just destroys games. I can see where they're coming from.

I mean, stuff like this isn't a fantastic solution, but there really isn't much of a fantastic solution.

Maybe it'd be possible to sell some sort of glorified USB dongle that a wide range of games could use that has a trusted computer inside and then stream sensitive data to it and have it only expose data to the host computer if it's necessary for the player to see it. That won't help with, say, aimbotting, but it could deal with "see through walls" hacks and the like. And you could implement some anti-cheat checking stuff on the dongle that you can't easily do remotely for stuff like aimbots, like get access to all mouse movements and such.

That could also be cross-platform. Have someone like Valve sell it.
