My understanding based on the notes from the IETF meeting last week is that the SRTP Key Exchange group met and is considering two options. They are exploring DTLS and ZRTP. (There was a third option on the table which they are no longer exploring) The biggest issue with ZRTP seems to be non-technical (ie Intellectual Property).
