(apologies if this is a double-post, the first didn't seem to have been sent)
Thanks for the info. I took it up as a challenge to finally learn a
little elisp. This is what I have so far, which appears to work as long
as I expand the entire subtree to be exported. I'd appreciate any
criticism since I really don't know if I'm handling things the best
possible way.

(defun ewd/export-properties (backend)
  "Export all properties whose names listed in EXPORT_PROPERTIES in the format:
   - <name>: <value> after each heading of specified level
   NOTE: 1st value in EXPORT_PROPERTIES is heading level"
  (if (org-entry-get (point) "EXPORT_PROPERTIES")
      (let* (
	     (export_properties (split-string
				 (org-entry-get (point) "EXPORT_PROPERTIES") " "))
	     (export-level (string-to-number (car export_properties)))
	     (export-list (cdr export_properties))
	     )
	(org-map-entries
	 (lambda ()
	   (next-line)
	   (open-line 1)
	   (dolist (prop export-list)
	     (if (= export-level (car (org-heading-components)))
		 (progn (insert "- " prop ": "
				(if (org-entry-get (point) prop)
				    (org-entry-get (point) prop) "N/A"))
			(newline)))))))))
