    Is there any way to limit the number of times that a PDF can be opened?


      I run a small publishing company and we want to provide exam copies of our books to professors.  At present our exam copies have the words EXAM COPY as a water mark on every page and we've also made the files so that they can't be printed or easily copied.  However, we'd like to also restrict these PDFs so that they can only be opened 5 times.  I've read about FileOpen but that approach seems a bit more complex than needed.  Is there any other way to restrict the number of times that a PDF file can be opened once it is downloaded?  Thanks in advance for any suggestions.
