Based on the share price (market cap) alone and it's recent direction, it would not seem that we have much completed, certainly not an alpha prototype.  Share price is only one indicator, of course, but I would say it's been an accurate one for many, many months.  I just don't believe things can be kept as secret as many here believe.

No rumors of buyouts at $3 or $4 with big shareholders told to resist such temptation?  LOL
