Ah, or maybe it was route who found it: http://www.zone-h.org/files/32/t_tcp_vulnerability.txt But I seem to remember something else found by the previous two as well. Anyways, why play fast and loose -- and thus make TCP worse -- when it already has a number of difficult to resolve problems. It is so easy to make things worse by adding extra gunk, yet we see people doing it all the time. Things should be kept simple, but they are not.
