DLNA is based on the Universal Plug and Play (UPnP) standard. DLNA-compliant devices running DLNA-compliant software can cooperate to store, stream, control, and play back audio and video steams. But: one step at a time, I can work that out later.The Digital Living Network Alliance (DLNA) is a trade organization that promotes interoperability among digital media products. Ideally I'd also like to be able to read information from the stream itself - for example, scraping the artist, album, and track name of the song currently being played and display that information on a serial LCD. Obviously the server will need some sort of interface to control what is being broadcast, but I've already got solutions in mind for that. In fact I even plan to have the filesystem be read-only, any temporary data that needs to be written can use a ramfs and be destroyed when powered down. There will be no other interface for the client whatsoever, whether it's a web-based client, a smartphone app, or whatever. The reason I'm looking for command-line is that this will be a dumb headless system: at most there will be a 16x2 LCD hooked up to the GPIO, a few rudimentary push-button controls, and a volume control. The server setup described is absolutely ideal, but each client in that system uses volumio - from what I can gather volumio really needs some kind of display, and the clients I have in mind will be completely headless. The idea was inspired by this thread: Narrow-casting with Raspberry Pi, Icecast and Volumio. DLNA does have other advantages though, so I won't rule it out. I think I'd prefer icecast, as I'd like to be able to have the same music playing across multiple clients simultaneously, and from what I gather that's not really supported by DLNA.

I'd like to set up a Pi0 to be a 'dumb' network music receiver: all it does is boot up and sit waiting for a broadcast from a network server, whether that's an icecast or a DLNA audio stream. I'm looking for some recommendations/pointers/suggestions on software.
