Breeze, I envision things this way. Suresh approached several potential customers for the interposer and let them know where they were in development, what the advantages would be if successfully developed, and they say, "wow, sounds fantanstic, Suresh, we'd be very interested in taking the interposer for a test drive, just let us know when you have the finished product."
Why wouldn't the potential customers for the interposer have interest? Naturally they would.
But thoughts of one of the other or a consortium of those customers buying us out? Well, that could well be the case, too, except that the share price/volume is not consistent with that kind of interest. Without a pretty darn good price run (up to around a buck, US), materially better than the nice run we've enjoyed recently, I'm going to stick with, "Sure, Suresh, please give us a call when it's done."
Nothing wrong with that, we just need to have the finished goods.
