I am a newcomer to Perl, but have much experience with postscript/PDF. I would imagine that the PDF::xx are for reading and generating the PDF file itself, not the trivial forms fill ins. Adobe has been working on the online forms problem for as long as there has been a web. (they went as far as to purchase a company about 7 years ago that did nothing but that) Adobe has an array of commercial solutions (trying to stabilize in the face of M$ft and open standards). although I am an implementor at heart, I little bit of money might go a long way to solve the problem well.
