I find it highly unlikely that a foe glass would just show people 
you *think* are your enemies, because as you say what is the use of 
that?  Where's the advantage? Who would want such an item and why 
would it be placed in such a position of importance?  This seems to 
me to be some fairly incontrovertible evidence that Snape is on the 
side of the good guys.  How else can you argue that he isn't without 
resorting to the unlikely "Well the foe glass may show who you 
*think* is your enemy."    

But I have another question:

Didn't someone mention that the broken Foe glass is then put in 
storage with the Mirror of Erised?  I can't remember.  And how does 
it break?  And who owns it when it does?
