A socket is unique with 4 pieces of info:
1) server ip
2) server port
3) client ip
4) client port

So you have many sockets all connecting to same server ip and port as long
as client ip/port is different, which they will be. If the same client trys
to connect with same local port twice, it will fail locally trying to grab a
local socket that is using same ip and port (IIRC).
