I agree that there is something different about Nunchi and MS. I have assumed that Pat Nunally developed this tech along with e.Digital for a reason. Meaning it goes hand in hand with previous Edig patents/tech.
If it stood alone with no prior art and need for other patents then why would he just have assigned the patents to Edig? Why not market and reap all the benefits and profits for oneself? He has been involved with other companies. Why Edig? I do not know for sure but..?
I am not a techie...just surmising here....
