Additionally, I failed to realise that you can put the "dhcp-hostsfile="
line in your conf file (to avoid potentially hacking a distro supplied
init file). I personally find this option more useful than /etc/ethers...
And yes it does work nicely in practice. In fact on my Mac, leaving
both adaptors live with the same IP address, mostly seems to work as you
might desire. It does seem to occasionally flip flop between adaptors
and on reflection I never thought to check that I'm not flooding the
network with spurious arp replies... Obviously you are meant to disable
one of the adaptors...
