Interesting experiment in flexible copyright

I put in an order, via a bookstore in North London, for a signed copy of Cory Doctorow's latest sci-fi novel, Someone Comes to Town, Someone Leaves Town. I've not read any of his books, but I thoroughly enjoy his blog posts. He's an activitist for fairer copyright and patent laws, so he's putting his money where his mouth is:

"This book is the first novel to employ the new Creative Commons Developing Nations License. That's a license that lets anyone living in a country that's not on the World Bank's list of high-income countries treat the book as if it were in the public domain. "
