As the IPv6 UDP Checksum relaxation effort gets instantiated (the draft
http://tools.ietf.org/html/draft-ietf-6man-udpchecksums-02 is now in
WGLC), could you look at the existence (or lack thereof) of UDP
checksums in IPV6 ? It would be good to have some baseline data to
see, if these become a problem in the future, what the state was
before they were adopted.
