Or, rather, just something I'd like to see tried - with the exception of the Successor States and places inside the Nexus, political boundaries in the Spiral are, to say the least, kind of vague. For showing that, I really liked the way the maps in DP9's Core Command were set up (for that matter, I really liked a lot of other things about that game, but that can wait until I can afford a copy) to show what were intuitively only rough indications of where the different states covered.
That said, aside from my usual inclination to fiddle with the political boundaries (I'm pretty sure these are from an older version), it's so neat I feel guilty complaining.
