Dual ethernet ports Due

The reason for all this: I have two other devices that need direct connections to and absolutely will not be able to use a switch (http://forum.arduino.cc/index.php?topic=253038.0) using the modified libraries?https://github.com/Wiznet/W5200_Arduino_Ethernet_Lib?for the wiz820io chip I found I am successfully able to connect with a single one to the google homepage download demo. Now I am trying to add a second wiz820io to my Due, and having difficulty figuring out how to make a separate instance of the Ethernet library that can use another SS pin. It seems that the w5100.h file defines the SS_PIN so I'm not sure how to make another one and then tell the sketch that it needs to make another client using the different hardware.
