I work for Motorola in Advanced Network Technologies.  We are painfully
aware of v6, both in Japan and in cellular IP.

Yes, I understand this, but a lot of things have changed in v4, and what
we are trying to do here is make v6 better.  v6 is not widely deployed.
We are trying to design things that will work seamlessly, so it is a
choice of whether or not to implement/when to implement.

This is multi6, not IPng, and multi6 is young.  Furthermore, we have the
chance to do things right instead of kludging them as we go along.  My
vote is for doing it right ahead of time.  v6 is still very young.  Anyone
deploying it already knows there is still work being done on it and that
some of this work may affect the future.
