With novels and other works of "general lit", eBook piracy is in its infacy. If you book is technical, such as high end software development, engineering, medical, etc., it's going to be pirated whether you put it out in an eBook or not. Eventually, Google will scan it and open it up 20% at a time, then you will get this email from a guy and his 4 friends demanding you send them the entire book in Word format to save them the time of pasting the 5 different PDFs together before they post it on their company Web server and send it off to a regional printer. Been there, done that, got the t-shirt. Some cultures view a single copy of anything as a "site license for the nation".
BTW, according to my research, they did eventually get the book to a printer.
Google book search is a very bad thing for the industry.
