Generally speaking, it is impossible, because aggregation removes
information.  I.e. the better aggregation is, the harder is to pinpoint
the exact location of the destination.

In other words, even destination-based charging (except very special
cases like ISP in the middle of nowhere connected by one wire to the
rest of the world) requires cooperation of many parties, since no
party has any accurate cost-of-transport information locally.
