For books and CDs -- and as the region coding system breaks down,
increasingly for DVDs as well -- only shipping costs and market
illiquidity protect the segmentation.  And markets are becoming more
liquid, even at the consumer level.  For example, I routinely order
the European editions of books from amazon.co.uk, for example, instead
of waiting for them to be published in the US.  This is exactly as
easy as buying from amazon.com; they even accept the same login.
