There are a few things to consider about Multicast:

1. Multicast associations can not compensate for changing network
conditions at each poll.

2. Muticast clients must use NTP authentication if they wish to control
which multicast servers they will accept. This requirement impacts
the autonomous configuration aspect of multicast (or manycast, for that
matter).
