Pippin:
Permanent Sticking Charm? But it doesn't matter where Quirrellmort takes
the Mirror, except perhaps to Nicholas and Perinel.  Voldemort will still be 
trapped if he looks into it, and it's unlikely that he can retrieve the Stone 
intact unless he does. 

The point of the whole set up isn't to protect the Stone, it's to trap
Voldemort, IMO. We saw that Voldemort used intentionally crude 
protections around the horcrux, apparently to put the thief
off his guard. Dumbledore, who knows that Voldemort has 
contempt for him, may have used the same strategy.
