Well, it could be used to provide cheaper hosting by subsidizing the 
bandwidth costs with CD sales, all controlled by the host and not the 
broadcaster.  This would require an in-line browser player, and not an 
external player.

It was just a thought.  Live365 does all this.  These changes would allow a 
Live365 competitor to use vorbis, without modifying the server code 
themselves.

It's a shame that Icecast could not put vorbis compatible tags into the 
stream, for external players.  The reason being that not all users want the 
metadata of every track to appear at the listeners end.  Commercials and 
jingles, for example.  Switching off metadata within the stream and using 
the http interface would allow us to do that.

While I'm rambling, is there any facility to display a history of tracks 
played in a browser via Icecast?  I believe Shoutcast supports this.

Certainly no major issues but just some thoughts I had.
