Hello, since Feb 2006 there is an ongoing proposal for an IETF standard on "TLS authorization". Unfortunately this standard is encumbered by a patent from RedPhone Security. While this company has agreed to provide a royalty-free license for implementors it has so far refrained from doing so for users. For me as an engineer this makes the proposed standard not only worthless but also -- because it's aiming to become an IETF standard -- dangerous. I only see two possibilities: Either RedPhone Security will provide a royalty-free license for both users and developers or the IETF must decline to approve the standard. In my experience the IETF is a reasonable organization who has so far always worked on standards that are both open and free to everyone. I will therefore assume that you will consider this issue carefully and decide on a reasonable solution, most likely one of the two I have just explained. Thank you! Leslie P.
