Originally we were discussing 'extremely dynamic' router changes. A crash
every few hours doesn't cut it with me for 'extremely dynamic'. There
are two things that should be done here. First, the microvax should be fixed.
Second, the software should have the list of default gateways that I keep
bringing up rather than just one.

Not a problem at all. You cache a route for each connection; if the
connection starts having problems or an appropriate redirect is
received, you recompute the route. It's very simple and quite efficient
if implemented correctly.
