I suggest nobody touch vircurex or cryptostocks with a ten-foot pole. This applies to shareholders and issuers. It's worse than recommending Gox with the evidence stacked up, As an asset issuer you have now decentralised blockchain based markets like CounterParty (XCP) https://www.counterparty.co/  or colored coin implementations such as coinprism to list  shares on, whereby you are not exposed to risk of fraudulent operators.
