Iñaki,
(As WG Chair)

I don't see these posting as productive for the WG. We have a consensus
on using SDP and Offer/Answer. This WG can't change the Offer/Answer
process. That is done in MMUSIC.

So please stop wasting peoples time with proposals that doesn't fit the
limits established by consensus decisions.

Regards

Magnus
