I agree, though let's consider HTTP. If a firewall is set to filter it, yet you are tunneling through with IPv6, you've bypassed your HTTP filters which may, among other things, provide AV protection. I recognize that there are plenty of ways to infect a machine. My concern is that teredo can bypass firewall security and relies upon host security to protect the computer. Unfortunately, not everyone utilizes host security and has dependence on network firewalls.
