According to the stackoverflow articles here

http://stackoverflow.com/questions/335607/how-do-i-make-an-outgoing-socket-to-a-specific-network-interface

http://stackoverflow.com/questions/8437726/can-python-select-what-network-adapter-when-opening-a-socket

binding to the local IP seems to be a windows only thing. I have tried just 
binding to the local IP, but my packets were from the default address (the one 
connected to eth0). After reading the 8437726 article again I think I may be on 
the wrong track anyway.
