I'm a newbie at networking. I understand the concept of multicast, but was wondering if it's reliable on the open/public internet?

It seems like sort of an edge case that different backbones or ISPs might intentionally break to reduce router load or generally segment the network for practical high-use applications.

Is my fear reasonable?

I've been searching for the reasons why IP multicast isn't widely supported on the Public Internet, and a commonly-cited reason is the difficulty ISPs have in tracking Multicast usage for later billing. Given this difficulty, since ISPs control the routers and they're not forced to support Multicast… >>> More
