what is the rpi2 system suppose to do? The LinuxMCE Raspberry PI system provides a full blown media director (probably sans Game Player ) - I've installed a couple of rpi1s at one of our sponsors sites and they work beautiful.
phenigma probably knows best what's needed in terms of configuration specialities he had to configure inside of LinuxMCE to make them work as good as they do.
if I remember right, it was supposed to be a "light" Nerve Centre... So also main server, not just Media Director...
