As the (hidden) maintainer of
PDF::Template, I feel it necessary to say that we are working towards using free solutions. We're also looking at addressing things that PDFLib doesn't do (such as Acrobat forms). Unfortunately, I have something like -4 hours /week to work on it. *winces* If you want to help, please email me at rkinyon@columbus.rr.com and I can definitely put you to work.
