SHORT VERSION:

Can someone tell me how I might be able to get a property value exported to
LaTeX?  Here's what I want to do:  I my reading and research notes in
org-mode.  I'd like to print them out to manipulate them manually before I
use them.  (Think: olde time 3 x 5 index cards, though I'll do it on A5 size
paper).  I'd like to define an inherited property in my org outline
containing my BibTeX key for the given book or journal article.  The idea is
that all of the notes on that book inherit the property (I can do this
already).  Then I want to export these notes to LaTeX and insert the value
of the 'bibtexkey' property into a custom latex citation command for each
exported node.  That way, when the notes are printed separate from each
other, I have the bibliographic information on each note.

EXAMPLE:

---------------------------------
* Notes taken while reading: Smith, Some-Wild-Book
  :PROPERTIES:
  :bibkey:   smith2009somewild
  :END:

** The Problem

Smith starts with a scorching analysis of the problem:

#+BEGIN_QUOTE
As I see it, this chaos has all arisen because of... (29)
#+END_QUOTE

** The Solution

Summary: Smith thinks that if we would all only listen to him, these
problems would go away. (235)

** Evaluation

Though Smith's audacity is unendurable, he does a few good points,
including...

-------------------------

I'd like to end up with a LaTeX file which will will print the above as
three separate (A5 size) pages. (I think I can do that).  But each note
("The Problem", "The Solution", "Evaluation") gets the value of the
'bibtexkey' property exported in the format:

\shortcite{<bibtexkey>}

immediately after the heading for that section.  I would do this with all
child headings no matter at what level.  Then when I take notes on another
item, its children inherit the correct value of 'bibtexkey' for it.

I think I have property inheritance worked out, and I reckon I can manage to
get org to export the headings how I want them (with
org-export-latex-classes), and I think I can mange to get LaTeX to lay it
all out right (it's LaTeX, how hard could custom layout be? :-).

What I want is a way to tweak org's LaTeX exporter to export "\shortcite{
<value> }" after every heading, with the value of the 'bibtexkey' property
inside it.

I suppose my question is: can anyone think of a way to do this without
making a custom LaTeX exporter?  Does the idea of exporting properties for
use in LaTeX output have enough value to warrant more general solution, for
example allowing placeholders for optional property values in (for example)
'org-export-latex-classes'?  Like this:

 ("\\section{%s}" . "\\section*{%s}\n\n\\shortcite{[[bibtexkey]]}")
