PDF Forms

Fellow PHPers, We've been working on various dynamic PDF generation things and now, we want to take things step further and place form fields in the PDF dynamically. Does anyone know if we can actually do this? I know that once a PDF is created with form fields (such as with Acrobat), we can populate those fields via the FDF forms and the FDF toolkit available through PHP. I've search the list, and as far as I can tell, and it's hard to believe, no one has really even asked the question. Anyway, if it's possible, could someone let me know. Thanks, -Flint
