Here's news of a cool use of XMPP via a tweet from kael<http://twitter.com/kael/statuses/804797351> : See: http://www.bbc.co.uk/blogs/radiolabs/2008/05/were_playing_your_song_persona.shtml
If you send your last.fm username to the BBC over XMPP, they will read your last.fm profile and then send you an XMPP message whenever they are playing a song by an artist you like. bob wyman
