The FlexLM system seems to work well in the UNIX world, and I believe there is finally something comperable in the PC world. The advantage of that system is that you don't ever have to go back to the vendor to get new keycodes should you need to reinstall, although you do need to go back to get new keycodes if you want to transfer the licence to a new machien. But this method of constanly having to go back to the vendor to unlock your software is just no workable, at least for me. I still have not bought Poser 5 and this method of copy protection is why. I'll stick with P4 for now but would upgrade in a heartbeat if this damned registration method went away. jon
