Hi folks,

I wanted to call your attention to a draft I just published with a possibly
stupid
idea.

https://tools.ietf.org/html/draft-rescorla-dtls-in-sdp-00

A nontrivial fraction of call setup time in WebRTC is the DTLS handshake.
This document describes how to piggyback the first few handshake messages
in the SDP offer/answer exchange, thus reducing latency.

Comments welcome.
