Who says the ICMP even follows the same path. There are already people routing
land v satellite by TCP port number let alone protocol. Then there are folks
who firewall icmp, and also those who treat icmp echo as a poor citizen
for their network, and those who proxy icmp replies to look better on
network performance charts...
Now do you want to trust anything but the syn/syn|ack ?
