Peter, Sirius, or Lupin: who was the spy again?

Officially, Peter. He admits that he betrayed Lily and James in PoA. 
(Well, he admits *why* he did it and *that* he was a spy, even if he 
never admits the actual betrayl.) (PoA, UStPB, p373-5)

Sirius and Lupin suspected each other. 

So why is this on JKR's website? (Extra Stuff, opening chapters of 
PS): "Other drafts included a character by the name of 'Pyrites', 
whose name means 'fool's gold'. He was a servant of Voldemort's and 
was meeting Sirius in front of the Potters' house. Pyrites, too, had 
to be discarded . . ."

Why was a servent of LV *meeting* *Sirius* in front of J&L's house? 

Is it possible that this is a Flint, or at least an artifact from an 
earlier draft in which SB was the actual spy? Or is a slip? 

I guess we'll find out in a couple weeks, maybe, but what do you 
guys think?
