I am a supporter of this initiative, but here's the elephant in the room.

I'm sure that I speak for most people when I say that for 2500 BTC worth of shares we would all like to see something running.  A working prototype or some sort of demonstrable technology showcasing what we can expect of a final product.

If I was buying shares in a flying car, I would like to at least see something that could float in the air as a proof of concept.
