I found one called [idocscript. I was thinking about buying it since it's only $24, but it seems to lacking some important features. For instance, the embed code and the download link reveals the location of the document and allows the user to directly access the PDF. That may be fine for some sites, but it is a problem for me since it would bypass advertising. I'm wanting my site to work more like scribd, for instance. idocscript may be a good start, though. Perhaps it could be integrated with [URL="http://flexpaper.devaldi.com/"]FlexPaper ](http://www.idocscript.com/)somehow.
