If Snape is good, how will he now help the Order? (more)

Assuming that Snape indeed was acting on DD's order to AK him, and
that 
he is still on the side of the Order, how will he help the Order?  It 
seemed from the end of HBP that no one from the Order is likely to 
trust Snape now that DD is dead at Snape's hand.  

I'm wondering how he (Snape) might work his double-agent role now, 
because it seems like his primary assistance to the Order was sending 
back information about the DEs.  Is there another member of the Order 
(again assuming Snape is on the Order's side) who might know as much 
about Snape as DD and is still willing to trust him?  Could it be the 
member of the Order we are to be introduced to more completely in Book 
7 (that JKR
has 
referenced in her interviews?)  Maybe Aberforth?  

Curious as how all of you think this might play out!
