Snape's Patronus

I think the speculation about the Patronus is wonderful support for 
Snape being a "good" wizard.  As we've seen, the patronus appears in 
the form of an animal (though Remus' is vague in that regard).    

And of course JKR would be revealing too much to say what it is.  
Again, we assume he has one because it seems to be a necessary part
of being in the order, and I would assume that Dumbledore knows what 
it is as well.

My guess?  A phoenix.
