So really, unless it's installed as a Windows Service or something, it can easily be circumvented. And if you're someone who really tilts like crazy, you're bound to say f%$& this stupid program, I know I can beat that motherf%&*er. But the problem is, unless the install is integrated into your poker client's programs, all you have to do is close the program(CTRL-ALT-DEL even) and you're able to tilt off your entire roll.
Now I haven't downloaded this yet to check it out firsthand since I'm at work, I'm just reading the site. I never have a problem playing above my roll, but I know a lot of people do, especially if they've been drinking or are on tilt or whatever, and that prevents it, as long as you have the program running, which brings up a problem. The feature I like the most is the bankroll Manager. I realize that you can turn on and off specific options like that, it just stuck out to me. OK, you won 5 buy-ins, better quit NOW! I just don't like that. I personally don't think it's a great idea to quit a session if you're running like God. One being Auto-Break when Winning a specific amount. It's an interesting piece of software, although I have a couple issues with some of the features.
