http://www.linuxquestions.org – I'm trying to setup a device that's acting as a LAN audio player running mpd (the mpd is controlled over LAN). It's basically a diy-NAS with speakers attached running headless debian. The device is currently up and running, but it's going to be given away to people who don't have a clue about linux. They'll need to be able to configure certain parameters of the device. So I was wondering... rather than giving these people full shell access, is there an easier way?
