Ricky,
I saw that the original question from Suresh is not expected the 'multiple connection' to the event. The server just has to notify the event to a client who registered oneself as the event listener.

As I said, the callback message in this application-specific case is affordable to be lost.

You have to encrypted the message.

No. It is much better than multiple TCP connections.

This is true is most cases. But the multi-cast can go over segments if IP multicast router is installed.
