live audio streaming for streamin providers

Hello,

We work with streaming to radio and tv statios, actually using shoutcast and windows media services. Now we want to add to our services flash media servers...

Questions:

1 - Could I use orban opticodec to send audio in aacplus format to flash server?

2 - How to create the application to make this?

3 - How to limit max listeners for a individual transmition?

4 - How to provid audience stats to final client about his individual streamin transmition?
