Ah... that's really cool. I hadn't realized you could run lisp in the 
header arguments.

I couldn't check the current export backend because the org markup uses 
beamer-specific features. The way to export the article format is to use 
the beamer backend, but with document class = article and a 
"\usepackage{beamerarticle}" line in the preamble.

But, I figured out a little hack: to put this at the top of the container 
file:

# ###### top of slide container
#+name: set-slide-flag
#+begin_src emacs-lisp :exports results :results value latex
(setq hjh-exporting-slides 't)
""
#+end_src

# ###### top of article container
#+name: set-slide-flag
#+begin_src emacs-lisp :exports results :results value latex
(setq hjh-exporting-slides nil)
""
#+end_src

Then I can test this variable in all of the #+calls.

It seems to be working. When I export from the slide container file, it 
runs each #+call once. When I export from the article container (where I 
have the calls in the container), it runs the calls for the article 
container but it does *not* execute the calls redundantly for the two slide 
show source files I have now.

Thanks for the tip -- that's working a treat!

I think I owe it to the org community to write up this workflow, after the 
project is over. The help from Nicolas, you and others has been invaluable.
