I remember trying to download Winamp 3 at school. The web filter would block it because it found the string 'mp3' in the URL. In retrospect the administrator wouldn't have seen any more use in allowing students to download a media player than to let them spend bandwidth on the media itself. Up until 2003 ~300 students split a T1. In that year the city started offering municipal broadband and the school switched to 2x 3M/256k DSL.
