Another option here is to add a defadvice to the actual sending command
(C-c C-c in gnus) such that if the command is called with a prefix
argument, then `org-mime-htmlize' is run on the entire message before
mail delivery.  To me this seems like a simpler solution than the above.

Ah, this sounds similar to the extension proposed by Dan and seconded by
a couple of others on the list.  It seems like the big question here is
how to convey all of the required mime information from the org-mode
buffer to the message body.

If I'm understanding correctly both you and Dan seem to be in favor of
exporting to mime and packaging up the raw mime information from the
org-mode buffer.  I'm leaning towards thinking that it may be easier to
simply bring the mail buffer to the org-mode file by saving it to a
temporary location alongside the org-mode file (so all links resolve).
It will probably take some experimentation to find out which approach is
more feasible/natural.

Agreed, this approach is simpler to implement however if the other
approach works I think it may be easier to use.  Again this question may
have to be hammered out on the forge of trial and error.

Thanks for the feedback.  There is clearly some more work do be done on
this front, but it is sounding like it will be a useful product once
complete.

Am I right in assuming that the current version is now working for WL?
