FWIW, there is a recent proposal which talks about enhancing TCP
checksums as well :-

http://datatracker.ietf.org/doc/draft-anumita-tcpm-stronger-checksum/

The above proposal tries to leverage on the TCP alternate checksum
option. My thinking it may be useful to have a "TCP generalized checksum
option" which can give the flexibility for a TCP stack to choose from a
set of checksum algorithms (of course the default stays what it is today
;-)
