Bitcoin was already deemed money when FINCEN started requiring MSB filings.

The interesting part of this ruling is that all the complex products out there that are derived from bitcoin will now be under regulation by the SEC.  Companies like ASICminer with public exchanges of their shares paying out dividends will now be subject to SEC regulations.  The exchanges allow for these securites to trade will now also have rules and regulations to comply with.  Any sites offering CD's or notes that pay interest will also have to pay close attention to the regulations they fall under.

I can see the argument being made that perhaps these securites are offered and solicited on the web in countries outside the SEC's jurisdiction, but any US based site or service will absolutely need to reassess whether or not they are complying with regulations.

Very interesting indeed.
