I have absolutely no experience with other "slide" engines in LaTeX. But I
think (as well) it's a good time to think at commonalities between these, so
that one extract the right model, even if we only support Beamer (which I
think is the best) in the first place, and maybe for ever. But it would maybe
ensure we ask ourselves the right questions.

I just know ('ve seen it) that Russell Adams (hep! ;-)) uses Prosper, one of
the old alternatives, before Beamer came on the "market". Maybe he could tell
us some interesting things about this planned construction?

Yes, I do have the same concern. An Org file for Beamer or a standard Org file
should have almost no differences -- except for the class. I think it's even
possible for small and standard slides show that there would be no difference
at all, except once again the length of sentence and the numerous headlines.

At least, the Beamer Org file would be the first mind map, or the skeleton, of
a real-document, would it outgrow from slides to document.

I don't know which exact representation it should have, but I'm puzzled by
headlines setting the width of columns, too.
