So basically this is what this thread is about. One needs a working 
Emacs instance and work in "push" mode to export any Org data. This 
requires dealing with temporary files, as described above, and some 
ad-hoc formats to keep whatever data I need to pull from org.

"Pull" mode would be preferred. I could then, say, write a script in 
Guile, execute 'emacs -batch' to export org data (I'm ok with that), 
then parse the S-expressions to get what I need.
