I suspect this can't be done within Java, but would be interested to learn otherwise.
I assume that java.net.DatagramSocket.send() uses a native sockets API to hand off the
outgoing DatagramPacket payload (and dest IP/port) to the transport layer. Typically
(AFAIK) sockets APIs don't provide facilities for an application to set the src IP addr.
