Thanks for the info.
I really doubt there is a military contract on any of the items you described. That would be a gold mine PR for the company. Why would they remain silent, If it were true?
In my opinion, any of the military products are dreams and toys and have a longshot to being commercially marketed.
There has to be so much bureaucracy and red tape to get anything into the military, i just assume it will never happen. If it does, I'll be thrilled to see it.
