Does Linux _really_ do this?  Shouldn't it route at the host layer

I think it does look for host routes before matching network routes, but
there needs to be one in your routing table. I believe when you configure
the interface the driver installs the network route only. i.e. by default
they will clash.

Like it I ping 192.168.0.1 it should return
the ping on that interface regardless of if another network device lives
on this network!  Or, do I have to explicitly set up host routes in the
routing table?

Yes, I believe you need to explicitly add them to the routing tables.

I guess what is the point of having multiple interfaces
on one board live on the same network, but even so, I would still think
it should choose the host route before the network route.  Any thoughts
on this?

You are correct, but you have to set it up manually. Or maybe it depends on
what net-tools package you use - the one I use doesn't add the host routes.

This is a good idea, but I would like to keep it simple, as they say
simplicity is the 'key' to High availability.

What could be more simple than removing all that really complicated IP
protocol overhead? :-) Cheers!
