This is a cool idea, actually. Not that there are likely to be a whole lot of commodities that this could be applied to that I can think of, but there are a few.
The problem is though, is it possible to have different allowances for the same commodity on different bases?
For example, the list of people ALG would sell nukes to is likely very different from who the Maquis would sell nukes to.
The Gate/Lane parts at Trenton would likely only be sold to Liberty corporations and others who are licensed, but the same wouldn't apply in Gallia.
Plus the whole system would have to be flexible since diplomatic stuff could change permissions at any point.
