Dear Darrell,
You've asked 3 questions. Regarding 1) & 3), someone from the community is about to work on it, so we on our own will have to find out where we are. We will keep you informed.
Regarding 2): That's a good question. Of course I have many ideas and concepts for the system and its elements, yet I've never looked at it this way, i.e. I've never tried to come up with a concise overall description. Could you explain me, what you understand under the term "Theory of Operation" (do you refer more to the technical aspect or to the application side, the purpose?), and I will try to come up with an answer.
Regards,
-marc
