Well, its entirely possible this stuff will be deployed in two scenarios:
* where its all done at the IP layer, eg policy routing, IPFW
* where its being done as part of a transparent ethernet bridge

That'd certainly be nicer. ;)
About the only thing I'm looking to add to this later on is to flesh
