Hmm... very, very nice idea. I suppose a modified version of the syncookies support, which instead of syncooking, requires a ping reply (sent upon ACKing the SYN packet) with the cookie to establish the connection would do it. Of course, anyone using this and not enforcing ECN is not making any sense ;) -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
