IETF, I am a web application Performance Engineer for a major SaaS hosting provider. My customers and I rely on free and open standards to build web applications that are useful, powerful and openly compatible with the widest possible range of software. In order for these standards to remain free, open and therefore useful, they must not be encumbered by patents. You have before you for consideration an Internet-Draft entitled "Transport Layer Security (TLS) Authorization Extensions <draft-housley-tls-authz-extns-07.txt>". The proposed standard described in this document utilizes a patent granted to RedPhone Security, the employer of one of the document's co-authors. RedPhone Security has threatened to sue anyone who uses this patent without their express permission being given in advance. Therefore, I urge you not to adopt the proposed standard. Please seek an open and free alternative. The internet community relies on you to serve this vital function, and we trust that you will make the right decision in this matter. Thank you. _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
