As an aside, there are currently 6221100 bitcoins in circulation (not counting ones that were lost, I suppose) and they are currently trading at around $7.50, which means Bitcoin has an implied market capitalization of around $46 million. Not enough to take over any banking systems anytime soon, but that is an awful lot of momentum for a weird crazy open source P2P thing.
