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.
