I really question how many btc users are going to be selling more than $600 of goods in btc....  Besides, this new requirement doesn't trouble gold dealers because of goods transferred *in gold* (though perhaps it should).  The problem is that any Joe or Shirley who sells gold probably sells more than $600 (About .52 troy oz at current rates).  Thus, if they do business with ten people a day, thats 3,650 forms to fill out.  (Neglecting deductions for weekends and holidays).  Yay, bureaucratic paperwork!
