On the Cara site someone posted a blurb about Venezuelaen and and Iranian officials approaching the Saudi oil minister to suggest a stop to pricing oil in dollars entirely.  Apparently the discussion with the Saudi Minister was done privately in between conference sessions...or so they thought.  The Saudi Minister's microphone was unwittingly left on for 40 minutes allowing others to listen in before it was turned off.  The Saudi minister is said to have refused this drastic measure because it would cause the dollar to crash doing more harm than good..
