Will Zfones protocol become an IETF standard?
Alan Johnston, Jon Callas, and I have submitted an IETF Internet Draft for the ZRTP protocol, which is used by Zfone to set up the cryptographic key agreement. Alan co-authored RFC 3261 which defines the SIP standard, and Jon is CTO at PGP Corp. You can view the current state the ZRTP Internet Draft here. Also note that the XMPP Standards Foundation has a protocol extension for “Use of ZRTP in Jingle RTP Sessions”, XEP-0262.
