Good question.
The Winklevoss twins will be at VLAB Event : Virtual Currencies: Gold Rush or Fools' Gold, The Rise of Bitcoin in a Digital Economy
http://www.vlab.org/article.html?aid=469
It should be interesting, there will be a Stanford Economist to provide a quick intro on Virtual Currencies (and Bitcoin). Kashmir Hill from Forbes Magazine, and the Tyler and Cameron Winklevoss (from Winklevoss Capital).
VLAB is a way to get entrepreneurs, industry experts, venture capitalists, and private investors together to exchange ideas and insights. Usually the panel consists of a moderator to lead the discussion, two small companies (doing something disruptive), an incumbent (larger company which might be threatened), and a venture capitalist or investor. Examples of small companies (which later became very big) include Google and Siri (bought by Apple).
If you're not in the Silicon Valley area, it will be videotaped, and available for viewing later.
I'll be there (Tony from Raspberry Coins - http://www.raspberrycoins.com)
