I have always assumed (dangerous I know) that Snape did indeed know 
the nicknames of the Marauders. It also occured to me that perhaps 
Snape believed that Lupin had actually given Harry the map or that he 
had inherited it from his father.  I don't think Snape would have 
allowed him to take it if he did not think it belonged to Lupin.  It 
has always been my belief that Snape didn't say anything to Harry 
about the makers because he had promised DD he would keep his mouth 
shut about Lupin and Black, especially around Harry.  If he had told 
Harry that Lupin was one of the makers, Harry might have asked 
questions Snape and Lupin were not supposed to answer.

In OotP, Snapes Worst Memory, the marauders repeated refer to each 
other by thier nicknames.  I can only find one example when Snape 
would definately have heard "Bad luck, Prongs" said Wirius briskly, 
turning back to Snape (pg 647 US ed.) IMO if they so easily used the 
nicknames in that scene, they would have used them easily everywhere; 
class, hallway etc.

I'm sure this has been discussed adnausium but how did Harry get the 
map back after book 4?  I also think the map might be quite useful in 
a way that has yet to be disclosed.
