 * The Viewer looks and works great, thank you! A couple of “How does it work?” 
   questions, please. I have a very large PDF file (32MB) that I want viewable but
   not downloadable, copyable or printable. Perfect match with your viewer, so far.
   Firefox appears to use a lot of real memory on my computer when I view the file(
   and, no surprise, it takes a while to load), so the question is “Onto what system
   is the full PDF file actually loaded (buffered)?” Is the data only on the server
   running WordPress and what actually gets transmitted to my client’s system across
   the network is just the page he’s viewing, or does the entire file get sent to
   the client system (in which case the data I want to protect by using the viewer
   is exposed on the client’s system)? How much of my data is actually sent to the
   client’s system?
    Second question, is there a way to instruct the viewer to open
   the PDF file at a certain page? Thanks in advance for your help!
