I like Option A since it doesn't add much in the way of external dependencies 
to Phonon.  Option B seems to do better at making the functionality to all 
Phonon users though.  Maybe just have a very thin plugin interface that Phonon 
could use to list visualization plugins with the application being responsible 
to host the plugin?
