Rather than XML, I would go for the Python Logging module. It supports
many log options, including user configuration and networking. Log
messages for parsing could be standardized.

Not sure we need this at the moment. Let's concentrate on functionality
and reliability first.

That could work for cron jobs as well.

Sounds like it would have minimal impact on code size if dbus was not
available for, or not used by, duplicity.

I think this level of complexity should be avoided. If a decision needs
to be made interactively, then we need to re-think the way we handle
errors, and make that part of the duplicity code base.
I'm in favor of the dbus functionality as long as the primary goal of
duplicity is not diminished, that of being a solid backup package that
will run unattended via cron or similar. If it happens to obtain a user
interface that does not in any way interfere with that goal, then we
have a winner.
