Hi Laurent!

        There are several ways to do routing via a known set of
landmarks.  Since each node is interested in the cheapest route to and
from each beacon, that's pretty easy to propagate (simply always
broadcast the best route you know about).

        Of course, if rates are expressed as "base + per-satoshi-amount"
then "cheapest" depends on the amount, so some heuristics will be
