I was just talking about the host mobility side of
things. The requirements say that the routing system
need not address host-mobility because mobile-ip seems
to adequately cover it (if we're wrong, we'd like to
know -- hence my note :-)

As to network mobility (where, loosely, we can assume a
1:1 relationship between networks and IP prefixes), it
seems to me that if the network moves, then its prefix
"appears someplace else" in the topology. That seems to
be "routing" to me. Hence the requirement that the
architecture be able to cope with it. Now there might be
a whole lot of ways to deal with it, maybe as a part of
the routing protocols, maybe as a separate protocol, maybe as something I
haven't thought of.
