Ahh, I got you.  Makes sense.

My mistake, I only remembered half of that discussion arc.  We
concluded that if you needed to go to a server to "refine" SDP, then
the application would be required to call create{Offer,Answer} again
in order to guarantee that the SDP was valid and usable.

Sure, as I understand it, the decision was to add a new constraint for
the number of ICE candidate sets (or components) that are opened.
This constraint would default to zero such that no candidates would be
opened.  The default for the existing candidate set would remain at
"all", which would ensure that setting this new constraint (either at
construction or through updateIce or whenever) would trigger the
gathering of candidates up to this limit.  Setting a local description
would trigger the collection of any remaining candidates, or the
discarding of any excess candidates.

This is all contingent on getting trickle ICE done, of course.
