Funny that you came up with an SMS-based "buzzer" -- a technique similar to this was used to gain an edge in casino blackjack decades ago. A custom microcomputer was hidden in the player's shoe, and IIRC they used vibrating motors to communicate the correct plays in one version of the device.

The webcam I think isn't there for an "illusion of honesty" but rather for a more personal / "human" game experience.
