Well, the problem has two sides.  One is that hollow is used to allow 
atmosphere to "leak" into an object.  The other is that it enabled media 
contained within an object.  Now, the second "feature" of hollow is fairly 
pointless.  If you add media to an object,why would you not want to make it 
hollow - because if you don't the media you specified just won't be visible.

The use with atmosphere on the other hand does make some sense.  But not the 
way it currently works because right now if you have an object with media 
inside, you cannot get rid off the atmosphere inside (well, you can with the 
object pattern and CSG operations, but lets not go there).  So yes, now that 
it is finally clear what the code does with hollow, we can make a better 
judgment about its usefulness.  But I will leave it at that for today...
