OK, that's what I figured. In that case, I'll continue working towards 
being the "primary" peer for the Arizona area codes, because I'm happy 
to accept the query volume for any other peers in Arizona and collapse 
their routes down to our area codes.

Yeah, I suspect we'll request our downstream peers to do exactly that, 
so we don't have to send them queries for every one of their numbers 
when they come into us. Would you mind commenting on my other precaching 
related posted? I'll help fix the documentation, if I can get my brain 
wrapped around how it's supposed to work :-)
