Is it possible to do a live talk show on shoutcast stream
 

I got approached by an astrologer and she wants to do a live talk show where people would call in and she would respond back with some advice. I have shoutcast internet radios going on, but i dont understand how we can intermix a live audio stream into the shoutcast stream. so far, I have only been playing pre-recorded content. Can someone give pointers as to how the live streaming functionality works please?

windows XP, it works well, after that, it doesn't work very well at all
