FWIW, we have some investigations along the general line of "what is a
layer" overall too:

But "what is a layer" isn't the point I was trying to make. Even if we
stick to the 7-layer cake, the question of fairness needs to include how
flows at each layer are aggregated, and what a 'group' is. I explored
this a little in RFC2140, but not to the extent that it needs to be
addressed here before a true solution can be applied.
