rewrite, rewrite, rewrite

The publication rights on my IBM DeveloperWorks articles (including articles about Test First Development, Profiling and Optimizing Ruby Code, and Debugging Ruby Code) have reverted to me. A friend of mine is a certified translator, and has offered to help me make them available in multiple languages. I'm tempted to update and polish them, add some more content (probably some case studies), and sell the combined result as a self published book. (With the contents available as PDFS and under some kind of open license). Would anyone be interested in something like this? I'm not fooling myself that this will make me rich, but it might help support a reading and writing habit that's becoming an expensive hobby.
