However you implement this, it's probably going to work more or less
like you're using one instance of rhythmbox and another player. You're
going to need a separate UI to control the second track, and you
probably wouldn't want to use the same player backend code as
rhythmbox normally does.

Maybe it'd be simpler to implement a rhythmbox plugin that provided
some UI within rhythmbox to control an instance of totem or similar.
You could then focus on designing that UI rather than dealing with
playback pipelines and basic controls.
