Many moons ago I created a software for the Windows PDA called CASE (COCOMO II Application for Software Estimation). I think the year was 2002!
And today someone sent me a link to a crack that had been created to get around paying for the application: http://wincrack.com/crack_Cocomo_II_Application_for_Software_Cost_Estimation_(C.A.S.E)_1.1.html
If imitation is the best form of flattery, shouldn't the act of someone creating a crack for your application, be just as flattering! ;)
COCOMO II was based on this Barry Boehm book.
ps: I strongly discourage you from trying out the link – I am sure it is a chockfull of trojans, viruses and other bad juju.
