Well, since there are so many programs out there that work
perfectly well with ipv6, it is hard to think of any real show
stoppers.
I can think of two major examples.
In certain circumstances, an IPv6 address can get embedded in a
user's AuthAuthorty. In most cases, IPv6 is not actually routed by
most of my customers (including a great many fortune 1000 companies),
and if the Password Server is on another subnet, users can't
authenticate.
In Panther, ipfw didn't understand IPv6. So 6 connections could get
around any firewall rules.
Both of these are mostly fixed now, but this illustrates a trend of 6
not being taken into account by developers. So unless the networking
personnel I'm working with are actually using 6 I always make sure
it's turned off on the Mac.
