An interesting article this morning on MacCentral details the rather complex set up for using an iPod as the backup for an FM radio station that has intermittent problems with its satellite feed.

The basics are that they installed the 5GB iPod as an on-site backup at the transmitter so that they would be able to switch over in a moment's notice while still providing an interesting mix of content from their library of live recordings made at the station's studio.

The switch-over is handled by a remote switch that can be controlled via a telephone.
