I am thinking of using Raspberry Pi to share Internet from a PC.
The Raspberry Pi would have a Wi-Fi module which would be running in AD-HOC mode. The Raspberry Pi would be connected to a PC through a USB cable. The PC is the only device connected to the Internet.
I plan to use my laptop to connect to the Pi on AD-HOC. The Pi would route all my traffic through the USB cable to the PC. The PC would route the traffic to its original destination and return the results back to me through the Pi.
The main problem I have with this scenario is the Pi talking to the computer through USB.
What I want to know is if my plan is possible/practical or impossible/impractical. If it is possible, would the PC host need elevated privileges to talk to the Pi through USB?
