Well, it unfixes the unicast :)...
I am planning to add some features in time, like a more verbose option,
that shows the moment of the broadcast.
If a system does not respond between two broadcasts, we can safely assume
it is not able to reply to the arp (in a switched network).
Currently I keep a table per 2 seconds, and any differences mean a new
host, or a host down. This information is fed to a simple ipvs daemon,
which then disables the rules by making the weight 0.
The daemon also accepts administratively down commands...
The cluster is now live since something end this december...
