Thank you, Ravi. That page was very useful. But what I need to do is limit
the Bit rate the user listens to on the server side. We want some listeners
to listen to the stream at one bit rate and others to listen on a higher bit
rate (paying customers). I imagine I have to set up two seperate publishing
points to pull this off. But I do not know how to tell a publishing point to
broadcast at a certain bit rate. Does that make sense?

Thanks,
Dave
