Not that I'm aware of. Although I'll add it's only suitable for some games. For instance it'd never work in bustabit, because the server needs to know the game outcome (bust) before players are finished making decisions (e.g. they can cashout in real time).

But if I ever got back into gambling (which I have no intention of...) there's no way I'd do it without such a system. The piece of mind knowing wins are legitimate is huge.
