So, essentially, there's no TOP part of the virtual bnet0 interface to move the packets up the network stack?

So the entire point of "nominating" a local interface is just to select the MAC address by which your machine is known on the Ethernet? I'm still a bit confused, though. Do you ifconfig your IP protocol configuration on bnet0 (or whatever you decide to name the interface), or on the LOCAL_IFACE interface?
