Unfortunately, New Belgium (makers of Fat Tire) does not even distribute nationwide in the US yet, so I wouldn't expect to see them exporting in quantity any time soon. But even if they and Sierra Nevada (and the hundreds of other great craft breweries) did export, I typically wouldn't buy it outside the US, because I would rather sample the locals when I travel. Though the rest of the world might appreciate American beer a bit more if they had a chance to try some of our offerings beyond Bud/Miller/Coors.
