The patronus thing, what about communication like the order use?
I wonder how that works, maybe patronuses (it's not 'patroni' is it?) are more independant? If they can be used for communication, even if it's just some sort of recorded message type thing, then they can probably be used for other stuff.

I thought the Order just used Patroni/Patronuses (I like the 'i' one better. >.<
wink to send messages like 'I'm here!', 'I'm lost!', 'I've got him/found him!', et cetera. There's no proof that they use it as anything other than a signal, like actually carrying an actual message like 'meet us at so and so place at so and so time. We've got an urgent situation to discuss.', although that would be wicked.
I do agree with Mrs. Voldemort as well. The Patronum is one of my favorite spells. It would be lame and wasteful for it to just be used to ward off two things. >.<
