OOP - "A lot more about Snape"

JKR said in the interview with Pax that we were going to learn a lot 
more about Snape, which got me thinking...

Snape already has bad feelings about Harry from the way that he was 
treated by James' crew back at school.  But he also shows every sign 
of trying to do the right thing when it really comes down to it - 
such as at the Quidditch match and helping to protect the Sorceror's 
Stone, etc..

What if Snapes conflicted feelings are from something deeper that we 
will learn about in this book?  

What if, through his activities a spy, he suspected that Peter 
Pettigrew was on Voldemort's side, but never told James or even 
Dumbledore because he was still resentful from the school days 
thing.  It might have been one of those passive-aggressive things.  
Maybe he didn't have absolute proof, so he justified to himself not 
speaking up about his suspicions.

Then, when Voldemort attacked the Potters, Snape would have suspected 
Peter, even though everyone else said the betrayer was Sirius.  I 
imagine Snape being torn up about it.  He tells himself that it isn't 
his fault.  That Sirius is the betrayer, so he must have been wrong 
about Peter, all the time knowing in his heart that he should have 
spoken up.

This would explain almost everything we've seen Snape do in relation 
to Harry and Sirius too.  He doesn't like feeling the way he does, so 
it comes out in his hostility towards Harry.  Harry is a living 
reminder to him of the attack.  People don't like to be confronted 
with a daily reminder to their guilty conscience.

It is also why he doesn't want to listen to HRH or anyone else about 
how Sirius is innocent.  This would be admitting his failure, and he 
isn't ready to face that.

Now, with Voldemort back and Sirius on the good guy team again, he'd 
have to face it, so Book 5 is the time for us to learn about this.

What does everyone think?  Could this be true?
