	This a thousand times.  Don't believe the claims of IPv6
support until you have fully tested it.  Almost no vendor is including
any IPv6 testing in their QA process and nobody is including it in any
of their support staff training.  Their labs may not even have v6
capability.  Some of our biggest vendors who have supposedly supported
v6 for over a decade have rudimentary, show-stopping bugs.  The support
staff at these vendors have often never even seen a customer using v6,
and they have no idea what it looks like on their own gear.

	A subset of these vendors will listen to you and fix the
problems.  Give them your support and loyalty.  I want to name names so
bad...
