Use android as xbox360 wireless adapter? I have a rooted cynogen mod Lg P500.

I can connect my xbox360 to my laptop for bridging a connection. but have recently moved to ubuntu so the bridging is a mission and a half.

So I was wondering if it was possible to use an android phone as an xbox360 wireless adapter.

By this I mean:

My android is connected to my networks wifi.

I want to connect my xbox360 to the android and connect to xbox live.

Is this possible?
This will almost certainly be impossible.  Your XBox doesn't have USB drivers for your Android phone.
