It's not possible to completely solve this problem with technology.
High level chess players (GMs) can win with just a few bits of information transmitted to them by a cheating accomplice (a cough if it's a critical position to spend extra time on, etc). Similarly, high level gamers only need the slightest of edges to win, and therefore only need the slightest of cheating.
That's why I think trusted user bases are the way to go. My initial ideas were naive, but I think the core idea is solid. If you had to pay $1000 to enter a "trusted club" which uses your hardware fingerprint, and all of your online interactions in a game were guaranteed to be with other people who paid $1000 to be in the club, would that not be a large deterrent to cheating?
