This is so completely wrong...

Multicast is cheaper than unicast from every resource perspective.
It uses fewer network resources for both content providers and
consumers.  It even uses fewer resources for network providers.

"The real difficulty of multicast" is that it's much more difficult
for ISP's (and presumably router venders) to support than unicast.
