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.
