Amiable Dorsai:
I've got to disagree--I think that Snape was moved primarily in order
to put Slughorn and his memories within reach of Lily Evans's (as
Slughorn thinks of her) son.  I think this was so important to
Dumbledore that he was willing to sacrifice Snape for it.  And I think
Dumbledore was right to do it.  The information that Tom most likely
split his soul into seven parts is absolutely crucial to Harry's quest.

Granted that it works on other levels; Dumbledore certainly is capable
of putting wheels within his wheels. Even Harry appears to think that
Snape is a competent DADA instructor: despite disagreeing with Snape
on the best way to handle Dementors, he's not tempted to start DA
meetings again. 

But I wonder if Dumbledore ever discussed the sacrifice aspect of his
transfer with Snape?
