listening -- just not understanding yet. I'd been monkeying around with exactly this idea using the USB CD drive from my wife's old netbook and a new RP2. haven't make any progress, but learned a bunch in this thread.
the ability to rip and store to temp and then dump to NAS OR play a CD would be a huge add on to Rune. OSMC has it built in, but that OS isn't what many are looking for in terms of a simple, headless player. having CD rip ability and pulling in simple modules for other streaming sources, like google play, amazon prime, tidal, etc. would be great.
wish i knew anything about programming and could help the effort...
