[Spread-users] Redundant ethernet spread configuration

If you are running Linux you might want to try channel bonding using the
trivial link equalizer. Then you can bond the two interfaces in each
machine into one interface (teql0) and run spread on that interface. I'm
reasonably confident that if one of the real interfaces goes down, that
the equalizer will send all of the traffic on the interface which is up.
You'd have to experiment with this, but it's one option.

Hope this helps.
