Yep, assuming you had a good enough Python lib for it, it'd be fairly
easy. You'd basically extrapolate a mailing list out to include XMPP
for your basic design. Lamson wouldn't have much to help with the XMPP
side, but it will help with the conversions.

I'd keep it simple at first. Focus on making it work for one person, a
single handler, and have it just do it all in one process inside your
lamson handler.
I'd probably have a model for your XMPP vs. email routing, that way if
you want to break it out into separate components you can without
changing your handler much. It's also easier to test this piece in
isolation then, or mock it out.

Study the examples/librelist source since it does a lot of what you'll
need to do to make this work. Take particular look at the
app/model/archive.py and app/model/mailinglist.py files. In archive you
have a couple of tricks for convertion lamson messages into json (or
plain python, or anything really). In mailinglist.py you have stuff for
routing around based on a django model's contents.
But, even if you just start with a simple handler that takes an email it
gets and sends it to your XMPP address you'd probably get pretty far.
