IMHO, we need it. We need that
convergence around some smaller number of mechanisms.

RTPSec BOF proposal for IETF 68
The IESG has received the following BOF proposal. I would like to get
any comments on it.
> RTP Security (RTPSEC)
> - Mailing list: http://www.imc.org/ietf-rtpsec/
> - BoF Session Chairs: Dan Wing, Russ Housley
> - Sponsoring AD: Cullen Jennings, RAI Area Director
> There are currently a large number of mechanisms defined or under
> consideration by the IETF to establish SRTP [RFC3711] keys between
> endpoints. Although an endpoint can implement several mechanisms,
> of these mechanisms are intended to provide standalone solutions and
> these mechanisms are not interoperable with each other. The IETF needs
> to converge on a interoperable solution to this problem.
> At IETF 66 in Montreal the Security and RAI areas held a joint RTPSEC
> BOF in an attempt to converge on a set of requirements and broad
> architectural approach for attacking this problem. The results
> can be found in the minutes  of that meeting. In the time since
> Montreal, a fair amount of work has been done on various aspects
> of this problem. The purpose of this BOF is to come to agreement
> on an action plan for providing a complete solution.
> In Montreal there was broad consensus on the need for some form
> of media-plane key management protocol (MPKMP).
> The two major open issues are:
> 1. Whether (and how) the signalling needs to be coupled with
> the MPKMP(s).
> 2. Which MPKMP(s) should be the basis for future work.
> Presentations should focus on architectural issues not technical
> details, which will be resolved in the appropriate WGs.
> Approximate Agenda
> Chair Agenda bash
> Chair Summary of Montreal Discussion
> Andreassen Status of MMUSIC SDP negotiation work
> All Discussion of signalling/MPKMP relationship
> Zimmermann ZRTP
> McGrew DTLS-SRTP
> Other protocols?...
> All Discussion of which MPKMP(s) to proceed
> Chair/ADs Wrap-up
> The expected outcome of this BOF is to resolve the above issues and
> to come to consensus on:
> - The set of work items which must be completed.
> - A work plan for each work item including where it will be performed.
