I'd like to do something a bit complicated with inline decoding of
message parts, and I'm wondering if Oort might already have some or
all of my desired functionality:

I sometimes receive messages, each of whose parts are mime encoded,
with the first part being the text/html version of the person's
message (yes, this comes from some Micro$oft mail client).

I have the following in my .gnus.el file to force text/html to never
be automatically displayed or encoded:

  (setq mm-discouraged-alternatives
        '("text/html"
          "text/richtext"))
  (setq mm-inline-override-types mm-discouraged-alternatives)
  (setq mm-automatic-display (remove "text/html" mm-automatic-display))

With this setup, I can type `1 b' in message buffers like I described
above in order to get a prompt asking me where I'd like to save the
html.  In most cases, this is exactly what I want.

However, in one particular groups, I want to be able to hit a key
sequence that will pipe this message part through a command which will
do a non-graphic formatting of the message.

I know how to do this:  I enter the following command ...

  1 K | w3m -T text/html

The "w3m" command does what I want, and the screen now shows the
non-graphic-formatted version of the html part.

However, if immediately thereafter, I type 'r' to reply to the
message, the formatted text goes away, and the resulting buffer is
empty.

What I'd like to be able to do is this:

Create a special way to "treat" an article that does the following
when I invoke the key sequence bound to this special treatment
command:

1. For all parts for which there is a known decoding mechansim
   EXCEPT text/html, just invoke that decoding mechanism.

2. For all text/html parts numbered <n> do this ...

     <n> K | w3m -T text/html

   ... and make sure that the resultant text appears in the buffer.

After this treatment, if I reply to the message, the text resulting
from the non-graphic-formatted html will appear quoted in the buffer,
so I can write a reply to it.

I could use the "hammer and tongs" approach and pound out the elisp
code I need, but before I do, does anyone know of any existing Oort
functionality that might be able to help me?

Thanks in advance.
