Good questions, I'll do my best to answer what I can and for anything I can't, I'll send Victor over your way to follow up.
We do have a bit of an established roleplay involving our Barge being refitted as a materials construction facility for a good bit of Civilian, Borderworld, and Zoner technologies. The thread that's used as the face of the business can be found here. We've got most of the Borderworld series snubcraft in there and the business actually works pretty well, since it's also our way to go about licensing our tech. In addition, we've been bouncing back and forth on the idea of whether or not we're going to buy a system of our own, and if we eventually do, it'll most likely have a dedicated shipyard or two as well as a production facility for the craft. For now, though, the Barge is our only current "production facility", and unless we get a system or something changes quite a bit from what we're looking at right now, there's no plans for any more OSI-controlled stations.
The only reason there's not more emphasis on production is that it really is a secondary role for OSI. We're primarily a shipping company, of course.
Of course, given that the Borderworld series is civilian in nature, I really doesn't see a good reason as to why limits should be placed on who can and can't use the tech. Someone wants a civilian ship instead of his faction's fighter? As long as the faction is okay with it, why not? Indies, of course, have their own leeway on this too. That's my opinion, though. If the Devs decide differently, we'd roll with that too. However, according to the lists, there's going to be dedicated Zoner snubcraft in .86, so under the guideline Curios proposed (and if I understand it properly), we'd also lose out on access to the Borderworld series. Have to see where that one goes.
