I imagine a setup where I use an android tablet computer as a remote control for my hifi system - at least for selecting music. I have connected a low-power, cheap and small linux computer to the amp. The low-powered computer holds all music on a USB stick, SSD or similar. The computer has no screen or keyboard permanently attached.
Can something like this work? All solutions I have found on the net require streaming from a NAS or the internet (internet radio) - e.g. Sonos. Ideas regarding hardware and software are welcome.
