I know that Freeworlds doesnt use Docking Rings - they use small Docking Buoys.
This makes the planets look 'cleaner' to me, no fugly docking rings covering the equivalent of thousands of square miles of terrain. Ships simply enter the atmosphere and land - no 'space elevators' or any such thing.
One could also put more than one on the planet. The normal 'lawful' point - and an 'unlawful' point on the far side of the planet. It would encourage unlawfuls to take the 'back door' - and encourage lawfuls to make patrols by orbiting the planet.
It would require a fair bit of work though - so perhaps a single planet could be chosen as a test for this?
