me,too i added a license system, that any programm i will sell it will have a own key and every time i sell my tool i change the key..if some one buy it and release it...i think he is stupid because he paid for the tool....
You should add an online Registration/Key Verification, because the person could just buy it once and resell it with the key you gave it.
Having a Database of keys will help you manage the clients much easier(You could make your software unavailable for that user, in no time, or change the key, for him).
