hehehe sorry Moose, I indeed have no clue how much it would be worth but I would be very happy with 500 million because this is equivalent to about 22 or 23$ per share.
And I believe my judgement of how important this tech is might be closer than yours. Remember how willing they were to help MTSX out last time? They could only get 0.35 cent per share (or was is 0.30 ..) of funding. They wanted to pay 0.40 cents but then only invest 10 miliion USD.
Now if this company would be worth far more than my estimates then 0.35 cents per share was a very bad deal. Clearly, Metal Storm does not believe themselves they are worth that much. So I would be VERY happy if they could sell the company for 500 mil$.
