multicast

My manager has asked me to assess what changes would be required to add multicast support to a socket-based TCP/IP networking program that is part of a trading system.

As far as I can tell, from the perspective of a Java program, it doesn't seem to matter too much whether the program is unicast or multicast.

Doesn't the Java networking API make all of this transparent? By this I mean, wouldn't the change be a simple one of simply adding additional destinations for the outgoing connections?
