I'm probably rather confused on this, but isn't the whole reason there are gates to the independent worlds, at least the ones between Liberty and Kusari, because they couldn't build them to go farther? I could've sworn there was a rumor or two that said it had to have a stopping off point. So, inrp, I'm not sure if it would be technically feasible, even if you get over the diplomatic issues.
Someone please tell me if I'm remembering correct, or just losing my mind again. :P
