I basically need the same: a document browser with a flipbook function. I was thinking to make it an addon to xenmediagallery, because that already has the needed directory structure, ratings, sharing, profile integration, etc. http://xenmediagallery.com/threads/embedded-document-viewer.389/
@Chris Deeming unfortunately does not have time to include it himself, so I am planning to have another developer create this. Let me know if this is of interest to you.
