MediaBox is even better it seems. In fact this one looks just about the right thing. If the view can be edited, to say, remove boxart view, which i don't need, or remove a few features like image viewing, that'd be great.
In overall, it's for a mobile platform, works with a good backend that is mplayer, has some pretty nice visuals, is fullscreen, and even meant for use with touchscreen stylus.
Great find! Now if we could find someone who'd work on this.
