How often have i wished for such an interface ..., yet there are lot's of 
problems with different formats and different requirements from each device, 
that will make this a rather complex task.
As you appear to have take an interrested in it, might I suggest that you go 
ahead and design and build a comprehensive implementation for the currently 
used formats?
