Forgot to answer this one point... Combined interface stats aren't very useful for a scenario we commonly entertain: what will happen if I move Big Customer A's ingress to ANSnet from ANS border router X to ANS border router Y? I need to know who they're talking to in order to answer that question. Typically large portions of the ANS mesh will be affected, and I need to know how.
