I'm sorry. but I don't know much about that. However, you could ask them about it. Most sci-fi authors I have spoken with are very open to answering questions, as long as they are addressed in a respectful manner. I don't know about Vernor Vinge, but I know that David Brin has a website that you could email him at.
