I distinctly remember being told this would never happen until we grovelled before ISO for an official currency code.
I think I remember that thread. That was probably specifically talking about currency conversion tools like Google's or XE.com (which is still most likely true regarding ISO). As awesome as it is to see Bitcoin put up on CNBC like this, remember that it's *MTGOX* that they're showing, which is awesome in so many ways but opens up entirely new concerns at the same time.
