True.

Depends. If he's in the Westin or some other colo, sure. If not, he =

I have to disagree with you here. Given the proportion of the IPv6 =
internet that is still connected via tunnels, your statement simply =
doesn't really hold.
I will readily agree that where possible, native connections beat =
tunnels. However, tunnels can be a cost effective alternative where =
native connectivity is not yet readily available and they still work =
quite well if properly configured and structured.
