Given how staunchly the greenback is defended against setting a defacto exchange rate with the euro (through joint trading of the two), I don't see that the powers that be would want a real world currency.

If a kilo of rice, or a gallon of petrol has the same intrinsic value regardless of borders, or (heaven help us), a days worth of labour will give the same amount of food, clothing, and comfort...the world would stop.
