We implemented a web based key distribution management system to handle this. It's not an insignificant overhead to implement and manage so it really depends on the module, it's value and market size. In terms of the problems you face without (or even with) key management, At one level you will have people who are generally honest and will purchase one license and then reuse outside the terms of the license, and then at another you will have those who will blatently copy, resell and generally have no regard to your IP. Chasing that down globally might not be your best day, especially if there are significant sums involved.

Thanks to both of you for your advice. We discard the systems based on your recommendations and we are planning to do a licensing system that request for a key in the first edition of the module. Who knows? Maybe this will be another module to sell.
