you mean in "real time"? there's no such option..

what you couuld do is to use the module playlist player to automatically load a playlist and play automatically, that's all..

I mean maybe you know other software for online broadcast ? Can u tell me, i'm interested of autoload playlist, it is possible ?

You might be able to integrate SAM Broadcaster if you know what your doing into MC. It provides the streaming and is what a lot of pros use, though it is not cheap. You would still need something like MC if you wanted to provide the pretty front end and website for it.
