[Icecast] Icecast source encoder that can handle http streams?

[Owen Mehegan]

I need to set up an icecast server which will stream out local MP3s  
sometimes and relay another internet radio station at other times. In  
order to do this, it seems like the icecast relay support won't help  
me - there's no way to turn that on and off without changing the  
icecast config and restarting the server. The only external icecast  
source app that seems to handle http streams is MuSE, and I'm having  
a hell of a time getting it working. Does anyone know of any other  
way I can accomplish this?
