I would be careful actually using teredo, as some of them (eg: Microsoft) have swaths of native IPv6 networks that are unreachable.
While I would agree in principle, in practice we have little control over what customers use.
I'm hoping they will correct some of the problems with it, but it makes IPv6 harder to use for some people as the Microsoft one does not appear to be well supported/connected. I'm not sure if there is an effort under way on Microsofts behalf to correct this, but I hope so.
This could be a host or relay-specific problem which may not be under Microsoft control at all. All the more reason for ISPs to run their own local Teredo relay. Antonio Querubin 808-545-5282 x3003 e-mail/xmpp: tony@lava.net
