Hate to toot my own horn, but… here I go a tooting…
I administer a server with over 80 WP installs, so the ability to update them all with a shell script was absolutely necessary. So I wrote one. You can find the code and instructions for using it here:

It does require you to be running Linux, and to have your installs on subversion already in order to update them. But really, if you have more than 3 or 4 installs that you’re trying to take care of, you need to be using subversion.
Hope it works for you. If you have any ideas for making it better, please let me know!
