Winklevoss twins and their investment

About a week ago the news was full of reports that the Winklevoss twins (two guys who made about $200M by winning a legal case in which they claimed that Mark Zuckerberg stole the idea of Facebook from them) have put $11M of their cash into Bitcoin. Which, ironically, they are storing on USB drives in various traditional bank vaults. All very well. But I hope that they've put another large sum into Bitcoin company development. Their investment is going nowhere if merchants don't start accepting Bitcoin, and that means that a whole slew of companies dedicated to Bitcoin services need to spring up to fill the need. That takes venture capital these days. I haven't seen any reports on the latter though.
