You're right about the web site, and FB has the ISBN correct (ISBN:044217715), but the book is called "Flow-Based Programming" - although their title does sound familiar....

I suspect nobody stocks it 'coz AFAIK all the remaining copies are in a couple of closets at home - but I would be delighted to send a copy to anyone who is interested - price negotiable. Amazon also lists it and uses me as a supplier, but it sounds like they're not too popular in certain quarters.
