Swiss co-founder of the cloud storage provider Wuala (bought by Lacie in 2009), Luzius Meisser, also plans to open up a Exchange Traded Fund (ETF) allowing investors to trade Bitcoins at a stock exchange. According to the preliminary plan he published on
http://www.bitcoinfund.ch, the fund should be listed at the SIX Swiss Exchange in Zurich around July 2014 with a market cap of 25 Million Swiss Francs (~26 Mio USD).
At the moment it doesn't seem clear if that project will be successful, but Meisser surely has some skills and credibility of his Wuala experience that might help to achieve these goals.
Interestingly, Meissers announcement did not make any buzz until now, even if his planned fund will be at the same market cap as the one of the winklevii's. Maybe nobody knew about these plans or he's just not so well known to the Bitcoin community as the Wwiis...
