The Opposite of a Horcrux; Harry's protection

I enjoyed your post, Del, and had been thinking roughly along the 
same lines. However, I believe that Dumbledore's death created 
protection for Harry, not Malfoy. A point which was mentioned twice 
in the book but never followed through on, is that Harry's protection 
from his mother is about to expire. Isn't this rather key? Is Harry 
to be left defenceless after his seventeenth birthday? My conclusion 
is that Dumbledore set up his own death as the required sacrifice to 
create continued protection for Harry into adulthood.

Cheers,
Nicholas
