With an adapter, you can run ethernet over usb in general.

There are usb<->ethernet adapters like these:

that you could connect through a switch or back to back with a crossover 
cable. I don't know if there are Linux drivers for all chipsets but I've 
used a few and they were recognized.

Unlike firewire, you can't directly connect 2 usb host adapters, 
although since windows vista now includes a utility to migrate items 
from an old machine over usb (like apple has always done over firewire) 
there are an assortment of usb<->usb adapter cables like:

but I don't know if Linux knows anything about them.
