Oof.  I wish I had found your mimelib a couple of weeks
ago.  :-)

You'll notice I've also posted a patch to Mailman
(SF#413752)
which adds an option to filter MIME attachments to plain
text
(delete binary attachments,  convert HTML to plain text,
...)
To do that (without defining new interfaces) I subclassed
MimeWriter --- it's a bit messy.   Using mimelib probably 
would have/will be cleaner. 

The Mailman patch includes a text/{richtext,enriched} parser
(same interface as HTMLParser) which you guys might be
interested in.

I'm about to head off for a (long) weekend of skiing, so I
won't
have a chance to look carefully at mimelib until next week.
Do expect to hear from me then, though.
