Even with a web frontend, I'm not clear on how I could get the audio from, say, youtube to go over the websocket instead of to the typical playback device. With something like Pulseaudio, I believe it's possible to stream to a remote host, but then musikcube would need a pulseaudio compatibility layer

You would have to download the youtube audio first (eg. using youtube-dl -x) then add that to your Musikcube library.

Then a web frontend could be served served audio over HTTP and play that back on the remote client.

Pulseaudio is system based audio, whereas here we are just talking about local audio to the musickube app.

Interesting idea to add pulseaudio compatability though..
