Hi Gert,

The initial question was "how to monitor the multicast Internet?", and
the answer is *hard* - you can't easily do it from just within one
network, as you never have a proper full view of multicast packets
flowing "to" and "fro".
Is there such a thing as "the multicast Internet"?
I've thought and talked about this before ...

The thing I was told is "nobody does IP multicast as bandwidth is cheap".
This is not true. Lots of people use multicast, even they are not knowing using it. Bandwidth is cheap, but provinding IP multicast is cheaper....

Apparently, people who need multicast-like features do it a few layers higher on the OSI model.

This is not multicast, but bandwidth/resource stealing or proxying....
