I think you misunderstood the question - what you have detailed here is a
list of customer communities that UUNet accepts, what Sean is trying to
find out is what internal localpref UUNet sets by default - do they
automatically give prefixes from customers a higher localpref than
prefixes heard from peers? I don't know for sure, but I'm thinking that
they do, which makes sense - otherwise it's possible to send traffic to a
peer when there could be a valid path for the traffic via a customer.
