From the developer: "viralPDF brings full re-branding functionality (and more) to all your PDF files. Unlike any other PDF customizing tool available today, it lets you use unlimited, brandable links and email-addresses, add an expiration date and more. It's a set of 2 downloadable Windows-apps that run on your local PC. Use it to turn *any* PDF file into a viral marketing tool: eBooks, special reports, articles,... you name it! "Only the brander as well as a test PDF file is included in the demo. The brander is fully functional and free to use. You'll need the full version if you want to make your own PDF files re-brandable."
