Most of this seems reasonably straightforward, but one thing that seems to require forethought is in-wall orbiters. I'd like to be able to control the system from touch panels in the walls, and I'd like these to be programmable, so that the setup is flexible. (I've looked at off-the-shelf systems, but they seem to tie you in to using a particular vendor's hardware.)
From what I've found on the LinuxMCE site, the Mini2440 seems to be the way to go for this. My question is, if I run CAT6 and power to a Mini2440 mounted in a wall, can I boot a Linux image from a server on this, so that I can create my own GUI to manage what the music server is doing? This seems feasible, but I'd like to be sure before I get carried away!
Does what I am thinking of make sense? Are there better devices to use for this?
