Thanks, I've not managed to get my hands on the book but have read a few snippets. I've certainly read as many of Colton's papers as I can find :)

For anyone who's interested, I've got an ever-growing Bibtex file at http://chriswarbo.net/git/writing/branches/master/Bibtex.bib which contains many references on this topic (all mixed up with completely unrelated stuff though!).

Thanks for the link. I'm also working on this. Would love to chat with you (or anybody else reading this), please contact me: juan at juan dot com dot uy
