Or maybe this could be achieved using a function in
`org-export-preprocess-hook':

,----
| Hook for preprocessing an export buffer.
| Pretty much the first thing when exporting is running this hook.
| Point will be in a temporary buffer that contains a copy of

| All the other hooks in the org-export-preprocess... category

`----

The function would be quite simple: Iterate over all headlines and
insert the desired reference.  This would, by the way, even work
without the property macro.

Something like this:

(defun dmj:add-citekey ()
  "Add citekey to all headlines in current buffer."
  (save-excursion
    (goto-char (point-min))
    (while (re-search-forward "\\*+[ \t]+" nil t)
      (let ((key (org-entry-get nil "mykey" 'selective)))
	(org-end-of-subtree t)
	(unless (string= key "")
	  (insert (format "\nReference: \\cite{%s}\n" key)))))))

Ah, Forgot about that.  Attached patch goes on top of the last one and
allows property inheritance.

Best,
