i think aaron's suggestion is a good one, possibly a hook into ppa-purge and software-properties-gtk to write a 'last-modified' file containing a timestamp that can be compared to a 'last-run-date' for update-software- center, triggering an automatic run of update-software-center by USC when the timestamps show it's needed... just throwing ideas at the wall, but the more transparent this is to users the better, your 'average joe' doesn't really want to think about software sources, my experience is that it's hard enough getting new users to realize that software can be installed from within an application as opposed to an internet download.
