I worked for a startup in 1999 that was doing just that. Neilsen's for
multicast. It was cool while I was there, but it quickly became clear
that the product was ahead of it's time. They now do event streaming and
I think they support unicast and multicast. Without a network that
supports it, multicast apps are useless.
