The fact that the one that can fly is invite-only makes me wonder if there would be ITAR issues with the guidance mechanisms that they have to put into it.
I'm not saying that there aren't lower hanging fruit reasons why they wouldn't make more of those, but you can see how the guidance necessary to make this move the way that it does could be dual use.
