And... the proposal for the dice WG to adopt that functionality
(regardless of draft) has been controversial. So I think that means
that one cannot directly compare encoding sizes, as we do not know
that a DTLS approach to multicast is workable. I'n not saying here
that one cannot depend on what's in these drafts, but rather that
we might not be doing an apples to apples comparison.
