Well, I guess that is the big question. Personally, I think most of  
the time I wouldn't mind having the show continue fully under the  
box, but it might be useful at times to turn that off, perhaps with  
an extra parameter to box-shadow to say if that it is knockout  
(defaulting to "not").

It is interesting to note that when combining text-shadow with  
opacity that the shadow does not show through the letters. It does  
seem as though there should be some consistency between the text- 
shadow and box-shadow.
