I couldn't find the original post to confirm, but I think someone threw out the possibility that Snape's patronus was either to do with Lily or actually IS Lily.  Is there any reason that a Patronus can't take on human form, and more specifically a particular human form?  I always just assumed it was an animal, but then humans are animals, too.  

Along the same lines, I know the OotP communicate via their patronuses (patroni?), but I wonder how.  Can they talk, or carry thoughts that can be read with occlumancy or something?  So many little details to cover in book 7 - how will she do it??
