That is a discussion about replacing the current routing
paradigm with a geographically-based routing paradigm
CA addressing is not about replacing anything but about
providing an additional option for people to work with.
The economic issues are for others to work out, and if
you don't try to reengineer the entire network, then they
are a non-issue.
