DMP had a product called Flo Media Publisher that we were selling in North America. It was a Windows based productt hat created flash books as flip books with roll overs for the corners, could have hard pages and hard covers, navigation by chapter, a "tree of files" for zooming in and showing progressively more detailed sections. It could do document comparissons (original compared to plate ready), preflight and report in the flash book as well as annotations. It was around 4,000 Euros. Unfortunately DMP is no more, but I am soliciting feature requests to build a new product along those lines. If anyone would like to give their opinions on what they would like to see I would be happy to talk with you. Best bet is to send me an email directly.
