I know that I've been a fan of consent via ICE, but with the decision
in Berlin to move to DTLS only, several of us have observed that
perhaps RFC 6520 might be a better alternative.

We've put together an exploration of the idea here:


The best part of this is that it changes the dynamics (for the better,
I think).  You don't need to send extra packets if you are actively
using the flow.  That means that 1:1 sessions won't need to spend
extra cycles or bytes on keeping the session live.

There are some gotchas for multiparty sessions, but I believe those to
be manageable.
