Not technology per se, but a fascinating copyright question

The Supreme Court has agreed to hear a very interesting copyright case. Publishers sell different, cheaper editions of their textbooks elsewhere in the world. The text is the same, the paper and binding may be different. Some enterprising American student leveraged this fact and had friends import these cheaper editions, which he resold here, at a modest profit, but way cheaper than the retail US price. A major publisher sued him for copyright violation, and the courts agreed with the publisher, but only barely. Now it’s gone all the way up to the Supreme court. Read about it here and in the Chronicle.  Comments in both locations are interesting too.
