Actually, rather than have to negotiate the TCP checksum type, one
could just assign a different IP protocol number to "TCP with
Fletcher".  If you get an ICMP protocol unreachable, then you go back
to the standard TCP.  Of course, then you might open a can of protocol
revision worms, like the window size to 32 bits...

Of course, this probably wouldn't work so great with the Berkeley
sockets programming interface.
