Inventor1, great post and great news! I'm glad to hear you still have a open line of communication with David, and hearing he was upbeat is a plus. I think we all tend to forget that as we investors are swarming a board with conjecture and guesses as to whats happening and wistfully begging for news....There is actually a company going through the riggors of real world cutting edge science and trying to make it a reality! Glad  to see some life back in this board!
