I'll put it a real as I can concerning Nunchi, the stealth concept.
If they don't go to the January 2013 CES show, which is the best place to demonstrate your products and services, to allow the players to see what the Nunchgi platform offers, -----then the Nunchi doesn't exist and it's another ploy just like we have seen over the last ten+ years.
Lead patent or not, that is not the controlling factor in marketing this industry service.
They have had ample time to fully develop this project.
I have asked too many questions concerning the business operations, strategies, and other areas of concern , without any response or regard to their fiduciary responsibilities.
