Pirating does incure other costs besides just lost sales. For example, if I have a pirated PPP and CL does not track serial numbers that well, I can call their tech support and get help on their dime. For products that are lead ins to online community stuff, this is a huge problem. I think CL has the right to protect their stuff. What I don't like is the idea of the checks on PPP. Putting these checks in a patch that's supposed to fix major problems is just wrong. Do that on Poser 5 instead. And I guarentee crackers will get around your security so saying CD keys are less effective than online keys is a little silly. Security is not about preventing theft, its about make theft inconvienent enough without hindering your loyal customers that only a small percentage of people can use the product.
