Bandwidth distribution per ip

That seems completely unworkable to me.  I would think most environment are going to have heavy hitting devices like firewalls and servers that cause traffic aggregation points in the networks.  If they shape on their customer's uplink port I don't see why the individual addresses matter at all.  I've never heard of that one.

As far as policing on an aggregated interface it would seem to be better to police at a different point where all of the traffic for a given customer can be policed together regardless of the physical port it is received on.
