Snape cannot become a spy again, IMHO.  Voldemort can always tell 
falsehoods.  So unless he truly is returning, then Snape is dead as a 
doornail.  If Voldemort DOES accept him, then Dumbledore would smell a 
rat since Snape would have to be sincere in his desire to return.

What is his mission?  I suspect it is the same thing that he did to 
gain Dumbledore's trust.  Dumbledore doesn't trust Snape simply 
because he became traitor to Voldemort.  If that were the case then 
Dumbledore would have told Harry when he asked because Harry already 
knew it.

Snape did something else, something extraodinary to get Dumbledore to 
trust him.  When Dumbledore turned to Snape and asked him if he knew 
what he needed to to ask him to do, Snape knew immediately what it 
was.  I really suspect that it is to repeat when he did way-back-when 
that caused Dumbledore to trust him.
