Once again, evilfry, you are gambling with your company's proprietary software rights. Is it worth losing them if you are wrong? Are you willing to bet your job and career that the legal advice you get from nonlawyer geeks on a free forum is correct? The issue of concern isn't violation of Knoppix rights, but the potential loss of your company's intellectual property rights. Isn't it worth the few hundred it would cost to talk to someone who knows? Find a good IP (intellectual property) attorney who knows software rights, and buy an hour of her time.
