I noticed that Emcaster only lets you bind once to the port and therefore you can have only a single subscriber.

Is there a way to have multiple?

If you add: SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);

To the PgmSocket it will let you have multiple subscribers.

I just tested it by dropping that line in the constructor.
