Return of Snape the spy

	I know we've speculated that Snape might use polyjuice potion to 
disguise himself on his return to the Death Eaters. I just thought of a 
twist on that...what if he originally joined Voldemort under an assumed 
identity in the first place? It's not so far fetched...I remember my 
father explaining that in his radical youth he'd been a card-carrying 
Communist...but the card had an assumed name.
	In that case, Voldemort might not know that the Death Eater he 
believes has left him forever is in fact Severus Snape...the only DE 
who would know is Karkaroff, which is why Snape encourages him to flee.
It would also explain how Dumbledore could safely expose Snape  in the 
courtroom and yet expect him to take up his role as spy again: no Death 
Eater besides Karkaroff would know that Snape had penetrated the Inner 
Circle. It would also explain why Voldemort didn't behave as if Snape 
was one of his servants when he was inhabiting Quirrel.
Feel free to pick holes in this, as usual
