Great! That's what I was hoping -- IMV in fact interface is the proper
abstraction, with MAC being one of its properties. However:

In practice will it have a NULL MAC or the same MAC as the parent
interface?

Really? I realize it's a bit of a normalization violation, but I think
it will make the code quite odd to have some Interfaces have Nodes and
others not!
