Speak of which, did anyone ever implement FIB compression? I seem to
remember the calculations looked really favorable for the leaf node
use case (like James') where the router sits at the edge with a small
number of more or less equivalent upstream transits. The FIB is the
expensive memory. The RIB sits in the cheap part of the hardware.
