To my knowledge, the Nixus fuselage was purchased directly from schempp-hirth. I'm guessing that the ASH-30 you are talking about was probably sold to one of the many companies taking open class gliders, chopping them up, and making high altitude drones out of them. An NDA sounds like just the type of thing they might ask for.
