"A $3 billion valuation/buyout of POET would put shares a bit higher than $18 US."

Correction, its closer to $12-13 US. And people keeping comparing POET to apps, etc. POET isn't there yet so you can't compare. A lot of these companies have been proven and have large revenues/profits and growth. POET isn't making any money...yet. So these comparisons just aren't appropriate at this time since POET has to be proven and accepted by the market first (generating revenue).
