[VOIPSEC] Phil Zimmerman to release VoIP Encryption Software(c.March)

[Christian Stredicke]

Tom, open source does not mean it is not proprietary. 

Zfone uses "ZRTP", which is currently his own proprietary protocol. I
appreciate Phil's work, it is surely a masterpiece. But it is too late!
The rest of this planet has agreed in the meantime on SRTP and TLS. Phil
should have contributed to RFC3261 (sips, tls transport layer) and
RFC3711 (SRTP). RFC3261 was published in June 2002, and SRTP was
published in March 2004. If Phil introduces it in March to the IETF, I
do not assume it will become an RFC too soon.
