Back in 2000-2001, I worked up a prototype of something similar using Adobe's FDF SDK [1] for PDF. We had a PDF-centric application that would render to PDF using an HTML -> PDF library and it was hugely problematic, so the prototype definitely made things a lot easier and, had the business not run out of money at about that time, it would have been the direction we headed with the product. So, how similar is this to FDF? Does it use FDF under the hood? If not, what are the pros and cons of this over FDF?
