easy

One solution is install streamer 5 times (to a different folder).
Like (example Values):
Code:
C:\Program files\Streamer1\ (Port 8466, TCP audio 8002)
C:\Program files\Streamer2\ (Port 8476, TCP audio 8006)
C:\Program files\Streamer3\ (Port 8486, TCP audio 8010)
C:\Program files\Streamer4\ (Port 8496, TCP audio 8014)
C:\Program files\Streamer5\ (Port 8506, TCP audio 8018)
Set every streamer to a individual port (p2p and TCP Audio). Then connect oddcast / shoutcast like normal. This way you have your own setup/folder for every p2p stream.
You can also install streamer once and just copy the folder. All you need to run streamer is inside the Installation folder (no registry).
But take care about your upstream limit of your internet connection
