History in the case of VLDI has especially been an accurate prognosticator of the future. That may change at some point, but highly doubtful, since the road signs do not point in that direction, rather in the direction of a rinse and repeat.
So far no one wants the product even as a niche product. If VLDI ever gets a real client, with a real commercialized product, producing real ongoing revenue it may be worth looking at as an investment, but until that happens it is dead money.
