Adobe Acrobat Restriction Javascript Plugin

Hi, We want to create some plugin for Adobe Acrobat that let publishers control own their documents are read. We want to restrict some operations (printing, copying/pasting, screen capturing) or add some new features such as destroy the document after a time period. PDF files may contains Javascript Code that restrict what the user can do with it. The document may also connect to a remote server to check policies using HTTP or HTTPS. Feel free to contact, I will answer any questions. Adobe Acrobat for windows and macintosh.
