Doing any streaming with unicast it pointless. Think about radio or video
(most streams are radio or video these days). The more popular it is,
the more bandwidth/server horsepower you need. It doesnt even scale well.
Think about the Bandwidth you need for only 500 "listeners".

But since since most suits and other clueless people think that
Internet == WWW = HTTP they won't even notice the existance of multicasting.
I work for a major ISP in Germany and I can count the number of customers
asking for multicast uplink on one hand. Heck, even the number of multicast
enabled ISPs could probably be counted with one hand.

Well...
