Moving facilities around on cargo ships? That would be so useful! Then you can prefabricate an entire huge planet's worth of facilities, go colonize a planet and drop the facilities there along with units and population, and instantly it's fully developed.

But because it's so wildly 'out there' in game terms it ought to be a special technology. Something you can't develop until very late in the game when you'll be thinking of using it to fill ringworlds and sphereworlds.
