A method for unicast packet-sharing includes providing a port configured to receive unicast and multicast messages; determining that at least one process is listening to the port; receiving a unicast message at the port; and broadcasting the unicast message to a listening address, thereby providing the unicast message to a proper one of the at least one process listening to the port. An example method includes utilizing a Berkley Sockets compatible API, and ensuring that all listening processes receive a copy, or selectively receive a copy, of the incoming unicasts.
