As much as I would want that to be the case, I'm afraid, it is only a matter of time when somebody tries to use (or has already tried) some transmitting device (like Google glass or an eye implant of sorts)
Back in about 2003 I played in a Chess tournament (live in person) and the top prize was £500; a huge amount of money for me at the time. I was determined to win this prize at any cost but I wasn't really any good at chess. However that was minor issue for me as I had a plan.
At the time phones with a vibration alert were pretty new, so I just stuffed one up inside my ass and my friend sitting in the crowd was playing out the games on a little chess computer (many other spectators were doing similar). Then he'd get the recommended move and keep phoning me and hanging up. Obviously I couldn't answer the phone (since it was up my ass and probably smelled a bit funny too)... but we'd both been in the boy scouts and knew Morse Code and he was sending me the messages using that
Easiest £500 I ever made.
