1) You need a client that will join/listen to IP multicast. I know Cisco
typically uses a video steaming technology to demonstrate this.
2) This is where the server portion of the software comes into play.
Hopefully some others will be able to give you specific softwares that
use multicast as I've never looked into packages for this.
4) Multicast is useful when you need to send traffic to multiple hosts,
but not all in a network. It uses less bandwidth than unicast and
doesn't interrupt all hosts like broadcast traffic does. With
technologies like CGMP, the traffic doesn't even have to be forwarded out
all switched ports.
