Dual use lighthack?

Question

Not really sure if this would be considered dual use. I know that the lighthack is only usable on the windows 7 consoles but is it possible to add an ethernet shield and have it work with both XP and 7 based systems. The ideal scenario is plug into a windows 7 system with usb but when i come across an older xp system hook up the ethernet to get it working. 
 
 If it is possible my next question would be would i be able to use a crossover cable to connect direct to the console or do i need to use a router?

The sketch would need to be rewritten in order to use it over Ethernet. It would not need a router but a switch is helpful. The light hack sketch is not easily converted to an ethernet based system. You would probably need a switch or other system to change the unit between ethernet and usb usage as well as a system to define the ethernet ports and addresses.
