Mike:
It's always been my understanding that the "blood protection" was a 
Dumbledore product. That's why we learned of DD's discover of 12 uses 
of Dragon's blood. Dumbledore picked Petunia's house because he knew 
an ancient blood protection charm that required him to match the 
blood of Harry's *ultimate* protector. And he picked this particular 
charm because he knew it would stiffle any attempt by Voldemort 
(though I still wonder if it worked against DEs). 

It was Dumbledore's charm that couldn't last beyond Harry's 17th 
birthday. But then, foolish old LV grabs some Harry/Lily blood while 
it's still under Dumbledore's charm. This somehow turned LV into a 
sort of Horcrux for Harry. The logic of this eluded me, but that's 
supposedly the reason why Harry survived the AK in the forest, 
according to Dead!Dumbledore.

I'd imagine, if it was Sirius that refused to step aside, Dumbledore 
would have brought Harry to 12 GP and handed him over to Ma Black (is 
that a revolting thought or what?).
