Multihoming scales and is reliable and easy, if it is offered end to
end by intelligent end systems, transport/application protocols on
which directly handles all the multiple IP addresses from DNS
(and mobility).
uh, no. multihoming done by end systems has a different set of problems
than multihoming done by routers. end systems have no good way to keep
track of changes to network topology,
There is.

also, it is very hard to support
mobility satisfactorily in this manner, especially when multiple
communicating end systems are moving at the same time.
Mobility is no more difficult.
seems like an exaggeration. FT apps do want to be explicitly informed
about network failures so they can adapt, and would like the ability
to make their own decisions about which links to use (given multiple
choices). but most apps are not FT, and to those that aren't FT,
address stability under changing network conditions is a boon.
Thus, most apps are taken care of by the transport layer.
