Wouldn't this require to set up a socket and connect it to each target
address? The point of the whole source and destination address
selection is it to avoid making connections with addresses/via
interfaces which might have problems. getaddrinfo returns a list of
addresses which a client program then tries in the order they are
provided. The address which has the highest rate of success and the
highest quality for the connection should be tried first. And all this
is subject to all the customization and configuration going in the kernel.
