I guess, blocking ports or defining ports to be allowed to users is not 
enough. Users are clever and smart from day to day. Once the originial and 
standard ports blocked by administrator, they use port forwarding sometimes 
to some kind of hosting server or dedicated server, and they still able to do 
music streaming.

If you checkout the greatest site, let say www.shoutcast.com, u can see lots 
of stations use port 80, it means connecting to radio stations would be the 
same as clients surfing to the web. 

I'm still thinking patch-o-matic STRING would be the best solustion for now ..
