for the sake of some nostalga

After being in CHF many yonks ago and then diving into MST in the early stages thinking I would soon be a millionaire, it has now been years since I was involved in either. Tired of waiting I suppose. But it pains me to see a great idea come to nothing after so many years, Gov grants, US interest and support, etc. So, out of curiosity, can any of the faithful tell me, did MST ever sell one of their weapons, or are they still all under developement? Thanks jwt
