As not all the shares allocated for private sales have sold yet but the 30.000 shares on GLBSE sold out within 4 days wouldn't it make more sense to try and sell part of those shares allocated for private sales on GLBSE ?

Keep it totally transparent so people know exactly how many shares are up for grabs (private and GLBSE)

That will also keep arbitrage in this 'pre-ipo' at a minimum
