Hi Jim,
I tried teredo and I found much easier to provide IPv6 connectivity to a NAT-ed segment enabling IPv6 firewalling on the firewall or add additional IPv6 capable firewall next to the IPv4 only firewall.
From security point of view Teredo relay can be used as a source of
malicious traffic. Teredo is difficult to deploy, since you need externel teredo server to rely on.

Teredo is not a nightmare.  But it does require coordinating functions
and nodes externally.  I am not advocating but I do not like to see
folks declare any hardwork or ideas as nightmares at this point we have
so little.  Teredo spec documents its limitations as all mechanisms.  It
also permits one to punch through the firewall which can be dangerous
without proper diligence.

Ok, things are starting to make a little more sense, thank you all.

I was ready to assign an IP of 2002: to a windows xp client
when I realized
that this machine is behind a firewall and has a nat'ed address of
10.0.10.x.  I would not think that would be allowed.

Is this a correct assumption?

Yes. For 6to4 you need at least one global IPv4 address on your router. Behind NAT you might try to use Teredo nightmare....
