This article has scratched only the surface of what you can do with udev rules. Any type of hot-plug event can fire a rule that can do almost anything.

The best overview for writing your own udev rules is Daniel Drake's “Writing udev Rules”, which can be found at www.reactivated.net/writing_udev_rules.html.
