yes.  if that "works" - by public-inbox literally parsing the pipermail
list structure, that's fantastic.

however...

i *believe*... after talking to Eric... that even that method expects to
see the archives (the actual messages) in "Maildir" format,
*even over the internet i.e. via HTTP*.

whereas what pipermail does - i think - is expose the mbox contents, directly, 
on a monthly basis.

i could be wrong: i don't honestly know.

i can't - i literally did "apt-get install mailman2" and followed
online instructions on "debian exim4 mailman2 howto" and that was it.

i didn't *understand* those instructions, i simply followed them.

> I mean how they exchange data. 

i *believe* - infer / deduce / hypothesise - that "mbox" format is used.
namely, that exim4 gets configured to "drop the incoming list email
into an mbox-formatted file" which mailman2 is then (separately,
in mm_config.py) configured (as per instructions which i read and followed
to the letter, mentioned above) to monitor.

now you get why i am reluctant to mess with the live setup.
