Slightly annoying problem

On your server, you can use port 80 and 81 if you are not webhosting with apache (or IIS in Windows). This will surely make it through firewalls for listeners - as far as your firewall is concerned (server side) - port 8000 and 8001 need to be open (if you do not use 80 and 81) as that is the default for WinAmp to use when connecting to your stream.
