Fetish -- err, Dice. A signature can be many things, what I mean by signature is an array of bytes. =/ In simple terms. Auto-updating addresses.
I have one question, what if were going on a vacation over the summer holiday, I have one coming up next week. By then I would have implemented and finished the signature scanner, but it might need some maintaining depends on how radically warrock decides to update. The way it was built should make it really easy to update if the signatures are changed or not working.
