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.
