A New Age of Sail?

I've been musing for a while to anyone who will listen that maybe, in the future, there will be a return to sail as a way to transport commercial goods. After all, as fuel gets increasingly expensive, why not transfer goods that aren't particularly time-sensitive by a completely non-polluting and awesome form of transport? Of course, there are probably lots of issues involving unreliable weather and more expensive crew, but still, a boy can dream, no?

Well, I'm apparently way behind the time. The return of sail has already started - there's a French company shipping wine by sail to other parts of  Europe, starting last year with a run to Dublin but with big plans for expansion. They've had at least one more ship running, but have chartered five. So far its mostly just carrying fair-trade, luxury goods, but even at that the French Association of Shipowners predicts that sailing ships could get up to 1/2 a percent of the shipping market worldwide (which is probably more than it sounds). Details here. 

I had know that they were  using fancy computer-controlled "Sky Sails" (giant kites, basically) to reduce fuel consumption on ships, but a return to actual sail for shipping is just so incredibly cool.
