This is one of several things I hope to see if SpaceX succeeds in crashing the cost/kg to orbit. I think it's difficult to overestimate how hamstrung our space program has been by the sheer expense of mass. New technology was certainly always going to be necessary, but there is so much that would be easier and/or possible if we could just get mass to orbit and weren't counting every gram. At current prices, it's hard to justify lifting dead weight just to spin.
