IP Multicast will play a prominent role on the Internet in the coming years. It is a requirement, not an option, if the Internet is going to scale. Multicast allows application developers to add more functionality without significantly impacting the network.

@dentangle I read the Wikipedia page (I had heard the name previously, but didn't know what it was in detail).
This is pretty cool, if I understand it I could potentially stream to millions with just the upstream bandwidth of one stream.
I'm not sure how the network is supposed to handle congestion and DoS stuff though, it opens up a whole new range of concerns
@Matter Yes, millions of recipients can be supported by a single tiny server, not just for streaming, but any kind of data.
There are challenges yes, but many classes of problem disappear too. For today and tomorrow's many to many applications, multicast is the way forward.
