Dynamic live stream -how? please help me.

Hi!

I have a question regarding the FMS version 4

We are in Polish. Recently we purchased Adobe FMS 4.0
We installed the service on the Centos system. Everything works-we can send a live stream, users can receive.

I have a request to all who are familiar with this issue.
We would like to prepare for live transmissions of including users of the Internet connection. Order depending on your links, you have the appropriate bitrate. Can anyone help? I do not know too much Action Script-o So I would ask if a simple translation.
