It would be easy to simply use crypt and the hostid to "brand" the sold copy to the machine in which it is installed, but it would also be potentially easy to break that mechanism. I have been looking for a survey paper that describes different copy protection mechanisms but have found nothing. I would appreciate any references or input. Also, if something like this already exists on one of the archive servers that would be even BETTER! What are other people using???? Thanks, dany guindi 512-343-1111 uunet!pencom!pensoft!dany
