[chord] Chord Simulator

[Frank Dabek]

Edward,

	I suspect that the "new" simulator does, or will do, most of the
end-to-end packet-level simulation you need: delays, drops, etc. Unless
you want to study something inside the network (Chord's effect on queue
lengths at routers, perhaps) I think that a port to ns may be
unnecessary.
