The RTPPusher module can broadcast to a multicast IP: [RTPPusher: package for pushing RTP/MPEG-TS unicast and multicast streams out of Wowza](http://community.wowza.com/t/-/93)

But, you can not use multicast over the Internet.

You can use a CDN (Content Delivery Network) service so that the only bandwidth you use on your network is to send the stream to the CDN.

There is a concept called “P2P streaming” that is designed to reduce client-server bandwidth.

But, for the most part, the only way to reduce bandwidth is to reduce stream bitrate.
