Simply, how to relay a stream (audio/video, doesn't matter) with VLC, _without_ transcoding (to save cpu)?
Example: If we have a video/audio stream, on the internet, and we want to relay that stream to our LAN users (for example), so that they don't have to connect to the internet, in order to listen/watch that stream, instead they just have to connect to our VLC, again, without transcoding.
See attached diagram for more info.
