Yes, this is why I said that the Offerer sends the full
list of candidates.  But if the Offerer already knows that the Answerer
supports this way of doing trickle, it just has to send one relayed candidate
in the Offer (can even be the one in the m= line and do not send any
a=candidates lines).  Let's call this 3/4 trickle :-)
