However unicast stream does not require state in the intermediate boxes (unless they are intentionally keeping some) while even single receiver multicast stream generates state all along the path. This will quite quickly limit the number of groups feasible.1/2, 1/3, etc the bandwidth for each additional viewer of the same stream? The worst case for a multicast stream is the same as the unicast stream, but the unicast stream is always the worst case.
