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. -- Shields. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
