Linux Radio Station Automation?

miazmatic asks: "I am one of the tech managers for my high school's FM radio station. We have been using Rhythmbox on Debian to play music after hours when no one is broadcasting. However, it took some pretty ugly hacks to get it to transmit the station ID every hour. We are adding a 600GB RAID 0 VG to our PC (P4 2.4/512MB), to which we plan to encode all our CDs losslessly. Along with this upgrade I would also like to find a permanent solution for broadcasting the station ID hourly. Has anyone used Linux to run a radio station before? Can anyone suggest a F/OSS software package or solution? Any help is appreciated."
