One other possibility that just occurred to me would be for the third
machine to have two ethernet ports bridged together. Insert the
machine in the path between the end-points somewhere,
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
dhclient br0
or something, and then run wireshark/ethereal on br0.
