I, Ali said:-

 I don't believe that there is any Canon evidence that rules out 
 Lily as a traitor. Lucius tells Harry that his parents were 
 meddlesome fools, but this does not in itself rule out Lily turning 
 bad.
 
Darrin replied:
 
 Support: If V-Mort truly had such a highly-placed mole as Lily, he 
 wouldn't have told anyone else about it, even Lucius, who, if he 
 isn't the right-hand guy, is very highly-ranking. So, Lucius, in 
 taunting Harry, would not have known Lily was a traitor.

Ali again:

At this point though, you have to ask why Voldemort didn't taunt 
Harry with Lily's betrayal when he was doing his evil overlord stuff 
in the graveyard. However, Voldemort did have rather alot on his 
mind then, and well, it wouldn't suit JKR's purpose to reveal that 
little gem in GoF, would it?

Darrin:
 
Denial: Lucius referring to the Potters as meddlesome fools 
indicates that they were actively fighting against V-Mort, not just 
kind of hanging around, minding their own business and having a baby 
that  would grow up to defeat V-Mort. So, Lily seems to have been 
part of the fight.

Ali:

I think that the Potters (Pl.) were involved in the fight against 
Voldemort. However, that does not mean that Lily didn't betray 
James. To take a current affairs example, a high ranking IRA member 
has only recently been outed as a spy for the British government. 
For a spy to be truly effective, isn't it the higher the better?

I can't really see Lily as a spy or a mole though. Perhaps it's 
because it's so anathema to the way that we - and Harry - wish to 
his parents, namely as heroes who died for their beliefs and their 
son. I imagine her sole (and enormous) act of betrayal was in 
handing over James to Voldemort. Arguably, this would not have been 
out of cowardice or change in beliefs, but desperation.
 
Darrin again:

 But I think the twist would make it too twisted. Lily's 
 sacrifice is, I believe, the pivotal event in the story (not 
 necessarily the books, but the saga itself.) One Muggle born woman, 
 apparently just through love, gave her baby the power to defeat the 
 most evil wizard of modern times. I do hope that is not tainted.

I hope you're right, but the more I think about it, the less "Lilly-
white", Lily appears to be.
