Not only did I find the book I was looking for... I found a site that had a tool to crack the encryption on the book... another site that had a cracked version of the book (for free download)... YIKES! There are a few commercial software programs that can bypass security however they cannot do so on a PDF with a set password to open the document. That being said, anyone who purchases the e-book can still pass along the file and passwords to friends co-workers etc. Whatever you decide I would strongly suggest disabling printing as someone can print/distill to PDF and create an unsecured version of the book. If Lulu is offering DRM "per book" pricing I would re-visit that as an option. Dave > On Thursday 05 April 2007, Conyers, Dwayne wrote: >> Bottom line... anything electronic can be accessed.
