Right, but the MBONE as it stands today requires alot more bandwidth than is actually necessary to do the job. > The MBONE serves as a means to control the traffic flow of audio / > video streams. It is a voluntary way of controlling the flow of audio/video streams, but it obviously doesn't do the job if you read up on it. It has been abused because it is enforced by other folks on the MBONE, not by any protocol limitation. > Again please do a bit more reading > if not lets take this discussion up on freebsd-multimedia mailing list > since thats the appropiate forum to discuss the pros and cons of > the MBONE. The topic at hand is the legislation of outlawing audio on the Internet, and why it's a good or bad thing. The MBONE is one implementation of both audio/video on the network which takes up a *huge* amount of bandwidth which could otherwise be used a larger number of non-audio/video consumers than who use audio/video. That is how it is relevant to the topic. Nate
