Parental Controls and SqueezeCenter

We have installed Squeezebox Booms in each of the kids' rooms.  This works great to be able to access all of our music in their rooms.  The kids like it as the presets are set to various childrens music, so they can easily listen to any of their music.

The problem is that our son is starting to explore our music. Some of the content is rated as "explicit", and we really would not want him coming across the music.  Now I am going to try and find a solution that would let me specify a list of artists that shouldn't appear on a given Squeezebox.  If this doesn't exist, I will look at writing a plugin to create this.
