[plt-scheme] Slideshow questions

1) Has anyone written code to output a Slideshow presentation as
   LaTeX (say, seminar style)? Failing that, any pointers on the
   easiest way to start?
2) How difficult would it be to create functionality like the
   full-screen mode of, say, Adobe Reader, which starts the
   presentation in a draggable, resizeable window, but allows the user
   to toggle between that and full-screen presentation with
   keystrokes? I often want to escape spontaneously during a
   presentation to use another application. I'm using OS X, and can
   move the full-screen presentation using Alt-right to expose the
   desktop and click in it, but that is awkward, and it doesn't allow
   me to minimize the presentation into the Dock. 

Thanks. --PR
