[arm-allstar] Wired tethering to phone (modem) usb or ethernet

The opposite. Use the phone as the router so to speak. What I am curious
about is making a physical connection between the pi and phone, so the data
tx rx from the pi, is connected to the phone. Like some specifically made
wireless routers, that have ethernet Jacks. I might just buy a Linux
compatible usb to rj45 dongle and see if it works. Whether I'd need a
crossover cable or standard, I guess I'll find out.

Back to one of my earlier questions. Does linux have the capability, like
windoze, to plug in a phone with a data usb cable, and use it like a
physically tethered modem?
