there is significant measurement and screaming showing the issues with
v6 tunnel connectivity.  geoff, of course.  and then a bunch of us have
been burned at conferences where the v6 was tunneled.

yes, it can be better than no v6 at all.  but we're well beyond the days
where we bet our businesses on tuneled v6 transport.
