Kuroyume, I can understand your point and I am quite familiar about what is available over the internet. Just use a simple usenet search engine and you ask yourself why you should pay for software at all. This is a fact and it will not go away anytime soon. It is clear that individual developers and small companies are hurt more than the big guys. But I also ask myself how many professionals who make money by using your plugin are using a pirated copy. The people who are using a pirated copy of your plugin probably also use a pirated C4D. They will nerver become paying customers.  If they had no access to a pirated C4D they would have no use for you plugin. Any efficient copy protection, maybe something implemented directly in Windows, would also prevent them from using a pirated C4D and because they would never pay the price for C4D they also would nerver buy Interposer. Can you give me an example of a software company which died because of piracy? I don't know any but there is a large list of companies which were killed by their competitors like Lotus, Borland and Fox killed by M$, Macromedia killed by Adobe and E-F Poser killed by DAZ, to name just a few.
