I don't know, I think installations would need something more permeant, like a space station. Or, for stupidly advance races, city ships. The most prominent in pop culture now would probably be Stargate Atlantis, though not a direct close of such facility just the idea of a moving space colony thang. (Along with all sorts of other mega construction projects!)
We've been having a discussion with Steve about allowing space colonies.
I think that space colonies are on his "round tuit" list.
A space colony ship doesn't have to be very high tech, just big (think cylinder with a radius of 1-2km). Technically, we can build them now but they would have the structural integrity of an empty soda can. Duranium would make a colony that you cold put engines on. I can't imagine trying to get it through a WP without a jump gate except at very high tech levels.
I'd love to run a space based empire from an RP standpoint.
