Does anyone know of any good guides to setting up either Raspbmc or OpenELEC headlessly. Due to the positions of my router & my TV its not possible for me to have a wired connection & plugged into the TV at the same time. I know Raspbmc needs a wired connection on first boot & I was able to leave this plugged into my router for enough time for it to update before moving it over to the TV, but of course I couldnt control it then. Can either of these be set up wirelessly?

Also, Im currently using Raspbian as a home NAS server. Can Raspbmc/OpenELEC continue to act as a home NAS server?
