My argument was that you don't need a collaborator for online cheating. It is simple enough to automate everything from just the video feed, and would be undetectable by any software running on the machine.
Use a hdmi splitter. Do image processing on one feed to register moves as they are played (regardless of delay), pass those moves into an engine, and show the output on a hidden display, vibrations to a butt plug, what have you.
For OTB cheating, it becomes more complicated, but I'm sure a computer can be made small enough, and register inputs in any number of ways, while the output can be encoded vibrations.
