		I have a problem with the statement "host should only need to
	know *a few* default gateways".  How does a host learn about more than
	one default gateway?  How does a host dynamically learn anything about
	routers without participating in the gateway protocol??  [I know the
	answer "ES-IS protocol".  I mean today.  now.]

Kent,

A proposal for an ICMP Gateway Discovery Query/Report pair has undergone
extensive review in an IETF WG, and is nearing (I hope!) RFC stage.
There is also a trial implementation underway.  So, this problem should
be solved soon. Meanwhile, we have to depend upon host configuration
information, as we always have.
