put simply , Until someone provides a real easy to install and apperate multicpoint to multipoint MULTICAST TUNNEL and pushs these interactive apps through it so as to bypass the worlds ISPs lack in will to turn on multicasting capabilitys to your average end users its never going to go anywere lont term really.

why Multicast tunel, simple, that was and is expressly written from the earlyest days in the internet to make passing single datastreams to many many people watching or interacting with that IP data real easy and saves MASSIVE bandwidth.

the worlds ISPs have seen fit to turn Multicasting OFF and filter it rather than help provide this protocol as found in every single ISP gade router and related kit, forcing you to use wastful Unicast streams only.

make the generic Multicast tunnel adn write your old unicast apps to use the tunnel and you instantly bypass the ISPs restrictions and perhaps help the real innovation and Muticast video streaming and true interactivity to take off.

sit back and say do nothing and you will never get true bandwidth savings or mass interactivity as it was ment to be with Multicast data streams to anyone thats cares to use it and tune in….
