I am not sure that such a thing exists.  Given the variety of hardware
and network topologies that exist, I am not sure how one would go
about achieving this.  Since we already have a reliable method of
configuring the ALIX over serial, I am also not sure that it is worth
the effort.

What you are really asking for is a script that is constantly running
and doing sanity checks on the network config.  This will only get in
the way of more complicated setups for little benefit, never mind the
overhead.  This idea also does not really help you right now, since
you don't know why the network drops and neither IP is reachable.  You
really want to get in there (via serial) and figure out what is going
wrong.
