This is really good news and or complete death of alt coins.    Nothing in between.   Hoping it is good news.  I have an accounting degree and I did my 2012 taxes based on just about exactly the rules they picked today.   Pretty much the only correct method to do them.  The business articles that mention this as a blow to miners are written for people that have no training in finance/accounting/tax law.  All necessary evils in a civilized world.
