You can do something like http://cooltext.com/ They have a queueing mechanism. In your case, any number of users can upload PDFs, those PDFs are then queued FIFO. The page the user is looking at can refresh itself every few seconds letting the user know how many PDFs are queued before theres and the estimated time to finish. Hope this gives you some ideas.
