I have this working now. Works great. I should have reported back with
my solution:


(defun my-org-export-preprocess-hook ()
  "My backend specific export preprocess hook."
  (save-excursion
    (if (eq org-export-current-backend 'latex)
	(let* ((tag "ignoreheading"))         ; Thanks to Nick for this
	  (org-map-entries (lambda ()
			     (delete-region (point-at-bol) (point-at-eol)))
			   (concat ":" tag ":"))))
    (if (eq org-export-current-backend 'html)
	(let* ((match "Qn"))
	  (org-map-entries (lambda ()
			     (org-set-property "HTML_CONTAINER_CLASS"
					       "question"))
			   match)))))

(add-hook 'org-export-preprocess-hook 'my-org-export-preprocess-hook)


The html customisation is incomplete for the moment (for the lack of
time :-p). My goal is to have custom styles for headlines tagged with
"Qn" (unanswered questions) and "QnA" (questions with complete
answers).

Actually I was also hoping to colour code my latex export based on a
similar philosophy using \todo[inline] and PROPERTIES. But I haven't
had the time to investigate the possibilities yet. I will put it on
Worg if I do manage to figure it out. :)
