From a programming perspective, you don't need another program as an aiming tool - "path" is already built into the game and is accessible in practice mode. When you switch to game mode I am guessing that a flag tells the game not to display the path option. All a hacker would need to work out is how to locate and change this flag. I had one of our work consultants "look" at how it might be done, and said it would be "difficult but achievable". I wanted him to do it so I could show FoD that it is possible, but he refused to hack the game under "moral principles". Thus to me the possibility remains unproven.
There is even another possibility - there could be a command built into the game, known by Operator and whoever he choses to pass the information on to.
