I was thinking wireless doorbell. I can hook up the GPIO pins for power and the doorbell signal and plug in a USB wifi stick. It can then buzz my phone (maybe via Jabber) to wake me up in the mornings when there's an early delivery. Even though the RasPi is hugely overqualified, it looks like it will be easier and cheaper than using a Arduino with a wireless shield. I'm also tickled by the idea of using a such a powerful computer for such a trivial task :)
