I am one of those who think that any human-made copyprotection CAN BE broken by another human. The case is just whether or not breaking the copy protection is "worth the job". Look for example at AutoCad. At least the versions officially sold in Finland are protected with some hardware kludge that plugs into the parallel port. I've heard about "versions" of AutoCad from which the code related to the parallel port "kludge" has been removed. As AutoCad is very expensive program, and a program of very good quality, this definitely has been worth of the job. I think if a program that costs just some USD 30 had some parallel port protection, it would not be cracked. The same holds true (I think) for programs of inferior quality. ..Wolf PS. Flames about supporting piracy to /dev/null. These were just my thoughts.
