Alan - I think there's a lot that we can't know yet re the technology and its potential market value. We may have something of value that yes the market may not being ready for -- but perhaps combined with other technologies could achieve marketability, either sooner or later.
Look at the 3DSim deal -- does it mean an immediate or certain traditional revenue stream? Likely not, -- but if our technology bears out their technology, and if they are valuable enough for a large, respected software simulation firm to purchase, then this could represent both a future revenue stream and at the same time may represent a window into the usefulness of PrintRite.
I don't feel able to assign a specific probability of success for PrintRite and Sigma. My opinion is that there's a decent shot there. I view this much like a VC investment that you do your best dd possible on, but can't wrap your hands around entirely -- decent shot -- but of course far from guaranteed.
