Hi Carsten,

Thanks for the pointer.  I was able to implement generic block
pre-processing on export using the `org-export-preprocess-hook' you
mentioned.  The resulting org-mode add-on is hosted at

http://github.com/eschulte/org-contrib/tree/master/org-exp-blocks.el

Currently it implements the comment processing I was after, and ditaa
image creation.  I think that it could also be used to implement the
src-code, block-quote, and verse exportation currently implemented in
org-exp.el.

Thanks for the advice, I think this is much better than my initial
comment exportation utility. -- Eric
