zgirnius:
I agree with you entirely about the security risks of discussing 
Horcruxes with Snape. But I think it is entirely possible Snape has 
independent knowledge of the subject...and if he's DDM, he would have 
said something to Dumbledore. If he already knows, it makes senzse to 
discuss this with him, since he is in a position to perhaps gain 
useful information, if he knows what he is looking for mroe 
specifically.

Why do I think Snape may know?

1) He was interested in Dark Arts as a student. I think he's read the 
same book Hermione found in the library which mentions the subject. 
ANd it doubtless made him curious. As a young adult he would have had 
opportunities Hermione did not have to investigate (trips to 
Knockturn Alley, talking to fellow Death Eaters and/or reading books 
form their libraries, etc.) I think Snape would ahve learned what a 
Horcrux is.

2) Snape is the likely source of some of Dumbledore's knowledge about 
the Diary. In the "Horcruxes" chapter, Dumbledore discusses 
Voldemort's great anger at Lucius Malfoy over the destruction of the 
diary. He says 'he was told' about this...Snape would be a logical 
source for this info, due to his closeness to the Malfoys and l;ack 
of any other source that we know of.

3) Snape helped to heal the effects of the Ring Horcrux. I don't know 
whether he needed to know exactly how the damage came about to heal 
it, but even if he did not it might raise his suspicions.
