It's a proposed money which will be comparable to the Euro, only for US/CAN/MEX should the dollar collapse here in the coming year or two.
While at the time it would be sold as "an improvement for trading, etc", it would be used to subsidize/save the struggling dollar, which mathematically only possesses 2% of it's initial worth from 1913, when the Fed was born and money was matched with gold. Those days are long gone.
Anyway, it's something to keep your eyes on. The fed kept interest rates steady for the 5th straight time this week. To raise them will kill the dollar, and to lower them will completely flatten the real estate market. It's seriously looking like a hurtin' is coming for the economy, and Jan 2, 2007 could be a very cloudy day for those with portfolios.
Be wise and keep your eyes open, fellow americans and getbig timewasters
