I love the iTunes library support, but would love to see support for other external sources as well, namely Plex! If I could point Vox at my Plex media server, I'd have access to all my music remotely which would be amazing. Vox seems like a perfect fit and would be the only desktop player to support this (currently music can only be streamed to the Plex medai center app, or via browser). I'm guessing that if a web app can stream the music, there's got to be an API exposed that Vox could hook into.
Thoughts?
