That might actually be a good idea in a way, I mean, the password Cracker is just a bit annoying, it's just 100% luck, if you could somehow make a mini-game of it, that requires skill, it would make hacking fun, time consuming, and hard. Therefore making minges get put off it. 'coz it's a pain just standing there and clicking. Plus you need to make it REALLY obvious that someone is hacking. Maybe have some hardware planted near the computer and connected and the person has to play around with that hardware remote or something.
Ideally, there'd be a query program on servers. Give it an IP and it can detect if the target computer is being hacked.
