RSA/PKP supporting Clipper? Where did you hear that? (It's untrue.)
Quote this paragraph: PKP will also grant a license to practice key management, at no additional fee, for the integrated circuits which will implement both the DSA and the anticipated Federal Information Processing Standard for the "key escrow" system announced by President Clinton on April 16, 1993. I'm not going to respond directly to him, since I don't know if you want him to know you reforwarded his mail. However, I would make the argument that if RSA really didn't want the clipper chip, they would license it to NIST in such a way that "all implementations based on our patents will be made available in software source form for non-commercial use". I'm sure legal language can be constructed which would prohibit hardware-only implementations. I couldn't write it though. Marc
