 Also, I don't see how he could have continued to spy while he was 
teaching at Hogwarts, much less have been absent from school 
(presumably without leave) to be a GH when the Potters were killed. 

Potioncat:
This is one of the reasons I don't think Snape began teaching until 
after LV was destroyed.  However, I'm sure teachers leave the school 
from time to time. DD and Snape could make it work. Also, if this 
involves LV thinking that Snape is his spy, then he wouldn't expect 
Snape at meetings or at events that would blow his cover.

I think this is very likely.

Potioncat:
But as we learn in PoA and Gof, Black didn't know that Snape was a 
teacher at Hogwarts.  Nor did he know that Snape had been a DE.  Nor 
did he know that DD and Snape were working together.

So, either James knew about Snape but didn't tell Black. Or James did 
not know who the informant was.  Either way, Snape would still resent 
the fact that James continued to trust Black. If YoungManSnape was as 
secretive as CurrentSnape, then it's very likely James did not know 
who brought the information.
