For those who aren't following the routing & addressing
discussions, there's been some discussion on MTU size
issues and tunnel-based solutions. See below, but it did
strike me that 2460 doesn't *explicitly* say "don't send
more than 1280 bytes unless you determine that a larger
MTU will work." It's implied but not stated.

I just re-read RFC 2460 section 5. Admittedly things are less
clear for IPv4, but it seems clear that IPv6 senders should not
exceed 1280 bytes (pre-encapsulation) unless they have succeeded
in discovering a larger path MTU.
Nice to hear some good news for a change. ;-)
Thanks,
Dino
