Sorry if this has been mentioned already, but I've been out of town, 
there are too bloody many posts to read, and I'm crosseyed from 
trying.  Anyway, if Snape is an accomplished Occlumens, could it be 
possible that he can close his mind to both DD and LV and work both 
sides against each other?

I'm not sure I believe this, especially since Snape is an antagonist 
in the truest sense.  And I was surprised I actually felt pity for 
him after his "worst memory" (not unlike Harry not believing he 
could meet someone he hated more than Dudley until he met Draco).

goodness!)
