You can use SO_REUSEADDR, but you might find that
the process that last bind'ed to the port will hoard
the data.  At least this is what I have seen.

You might be better off implementing something where
the 2 client processes register a with a server process which
in turn opens the socket, binds, then subscribes to the
multicast groups.

Hope this helps,
Tuan
