How would you "switch" the users, I mean on the fly? Rewrite the 
configs so that you define the mountpoint from with the main server 
relays anew and give icecast2 a SIGHUP to re-read config?
Anybody tried such things in practice?

Together with this topic I might bring up the topic of a radio 
automation system. Maybe there are some tools out there, freely 
available? I don't want to / can't purchase a commercial system for 
3000$ or something to do automation. But it should support things 
like automatic fading based on the songs (endings / beginnings of a 
song), be able to use categories to build a well-balanced playlist, 
play jingles from time to time etc. Also a Linux-solution for 
combining this with live-talk (moderation) would be really much 
appreciated. Does somebody know of any such solution out there?
I heard from time to time that many people of you are doing >10 
streams. Do you just use playlists - or maybe tools like the above 
mentioned to have fading between tracks etc. to make it sound better?
