the packet stream to figure out who is using the most
bandwidth and when. I know all the MAC addresses of the
individual machines so I can trace them that way.
I think you are thinking too hard, unless it is intra-network
traffic you are concerned about (unlikely as you mention
'outside').
bandwidthd if you can hop up to the IP layer
