@don_falcone,

I also find it very interesting.. but at least we can do code analysis with the source in front of us. In a previous life, I used to do that using a hex editor (long live HIEW and MS-DOS in general!), and I actually developed a sort of "talent" for cracking shareware without even bothering to use a debugger.

I'll see if I can get some time to inspect libcal.so. Nowadays people are very sloppy and leave debugging symbols all over the place..
