The most recent draft for teredo only requires use of 3FFE::/16 obliquely:

2.6 Global Teredo IPv6 service prefix

   An IPv6 addressing prefix whose value is XXXX:XXXX:/32.
   (TBD IANA; experiments use the value 3FFE:831F::/32, taken from a
   range of experimental IPv6 prefixes assigned to Microsoft.)

Draft-huitema-v6ops-teredo-05 expired last October, and I can't find it
in the I-D tracker. It doesn't seem like it would be too much of a
stretch to update that section if a revision was in the works.

As from: http://www.rfc-editor.org/queue.html

aka in queue waiting for IANA to act upon it.
(IANA = RFC-Editor/IANA Registration Coordination)

In real life, does anybody actually use terado? Are there a well-known
set of teredo servers and relays for which some arbitrary, large ISP
might measure traffic levels? It seems like if it was enabled it would
be possible to measure traffic from teredo's bubbles, even if nobody was
actually using it to retrieve content.

Check http://www.sixxs.net/tools/aiccu/brokers/ which has a list of most
/all (send mail if you know more :) public tunnel brokers and all other
related items.

Only AS31701 (Consulintel) and AS5511 (OpenTransit / Wanadoo France) are
announcing the 3ffe:831f::/32 prefix though.

But from my logs (including ipv6gate.sixxs.net ;) I don't see any
traffic coming in from it...

Greets,
 Jeroen
