  Unfortunately, it may not be possible to modify net.agent to do this
automagically because it is non-trivial to determine if there's anything
attached to the eth0 port. Your pointer to 'route del ...' is valuable!
Thanks, Matt.

  The parsimonious solution is to do this manually when I want to use the
wifi interface rather than the wired interface. That is, when I'm away from
the office. But, you've given me the idea that I can write a script that
brings down eth0 ('ifconfig eth0 down'), deletes that route, then brings up
eth1 and attaches the route to that interface.

  It doesn't need to be automatic, any more than my connection to a dsl port
in a {h|m}otel. In this situation I su then run 'dhcpcd -d eth0' and away I
go. I'm just as willing to run a script that changes the interface and route
from eth0 to eth1 when the wifi card is in place.

Excelsior!
