I share the concerns of the FSF [http://www.fsf.org/news/reoppose-tls-authz-standard] and Simon Josefsson [http://www.ietf.org/mail-archive/web/ietf/current/msg55059.html] about the TLS-authz draft. The usefulness of the proposed standard http://tools.ietf.org/id/draft-housley-tls-authz-extns-07.txt appears to be severely limited by the patent disclosed in https://datatracker.ietf.org/ipr/1026/. For example, if the authorization is intended to play a role in the enforcement or implementation of "any legally recognizable and documented agreement between two parties," then RedPhone Security apparently asserts patent infringement in their IPR. The offer of "fair and nondiscriminatory" license grants is unclear, but similar offers in the past have excluded use in free software. Please continue to oppose this standard until RedPhone's patent is invalidated or they provide a royalty-free license for all users.
