This can be quite a religious argument, but speaking from experience of code that's been rigorously hacked time and again, the only effective way to disable parts of your code is to not have that code in the executable. E.G. a compile a demo version, and a real licensed version. Having code execute dependent on some switch, regardless of the number or sophistication of the switches, can be hacked. Period.

I disagree. If it's based on a tried and tested (and occasionally formally verified) crypto system, knowing the algorithm doesn't lead to a crack. Weaknesses would come through bugs in the framework (or incorrect application of it), and the more people who can see the source the greater chance there is that good people as well as bad can find the issues. Good people fix 'em.
