All valid comments.  Can't help but think they must be real close to signing a deal with someone though.  

Here is a link to yet another very recent research paper published this year that also supports SMN's product offering -> http://aip.scitation.org/doi/abs/10.1063/1.4974616

As an aside, I know a guy who flys helicopters in the military for a living.  I asked him whether he had come across SMN's product, to which he replied no.  But he was intimately familiar with the cracking problem that SMN addresses.  He had a look at SMN's product and thought it was way far superior to an existing product being used to some extent that delivered so many false signals that they had to stop using it.  To me this suggests that the military are indeed a very genuine prospective client.

Overall, it looks like this product will get commercial traction soon.  The question is of course, how much and how fast?
