think of it as all the XOs plugging into the same ethernet hub. no
router needed, and they all see each other's traffic. you just plug
in and start talking (of course to really do that, you'll need a
link-local address, or a static address, since there's probably no
DHCP). it's quite similar to the mesh -- what the mesh adds is some
topology awareness and routing, so if A can see B and B can see C,
then B will forward packets from A to C. that can't happen with
