An expanded arena mode would-be useful for this sort of thing. Especially with such long build/immigration times. I don't mind those times inthemselves, just difficult to test things.
I'm happy with Haxus' choice of (2). The slightly lower limit for ringworlds is fair enough. They have so many arcs anyway; defences can easily overlap.
We might also want to bear in mind any future productive capacity added to spacecraft. It would be strange if they could run as many processes as the largest possible planet. Solution 2 seems to make more sense of that.
