this would expose to the visualization the implementation detail that there 
are N different sources of data being agregated. in this case, there wasn't 
even a change in the dataengine's exported set of sources (which is the whole 
point of dataengines).

in the case of weather, which is the same concept, the engine itself supports 
plugings and things are agregated in the dataengine that the visualization 
interacts with.

as for backporting the change, since this can't interfere with amarok1 (which 
used dcop, and not dbus) and that amarok2 is evolving software that hasn't 
seen a final release, i think it makes sense to backport. as it's not critical 
for 4.1.0, we should wait until that's out the door and do it for 4.1.1.
