Great! If you're at Pycon, come sprint with us. If you're not here, we're
going to at the very least be active on #mailman for virtual sprinters.

I think it would be nice to have a rich HTML-based digest format, and I
believe it should be fairly easy to put such a thing together (read: branches
welcome!). If you look in mailman/interfaces/member.py you'll see that
there's a DeliverMode enum with a summary_digests flag. This is really a
placeholder for essentially what you're suggesting.
MM3 has a separate DigestRunner it uses to compose digests when the time is
right. It does this to move the work of digest creation and sending out of
the main processing runner. Right now, it's fairly hardcoded to just the two
existing digests (MIME and RFC 1153), but with a little refactoring and
interface definition, it could be easily generalized to include another style
The important methods are .add_toc() for adding a table of contents,
.add_message() for adding a single message to the digest, and .finish() for
producing the email ready message tree. There are two classes implemented
currently MIMEDigester and RFC1153Digester. I could easily see an
HTMLDigester or some such.

This should be doable with an HTML supporting mail reader. I think may be an
RFC for this kind of inter-part linking (can't find it right now;
multipart/related or something like that).

I have no idea how you'd do this in a cross MUA way. That to me is the
biggest risk with something like this. For those who choose HTML/Summary/Rich
digests, I'd like to see broad MUA support, but I honestly have no idea of the
worry about text-only, or text-preferred mail readers though because users of
those won't be selecting HTML digests.
