I have a customer who has teenage children. They play an online game. When she is not home they spend to much time on the game. She wants them to be able to use the internet, so I can't shut the internet down, and she wants them to be able to play this game, but she wants to limit the time they can play. Example, I need a way to not allow them on the game after 30 minutes of play, but still allow them on the internet. Any ideas?
