Now you're talking. IMO in a 2-node cluster, a node that kills itself in 
response to, say, losing link on eth0 is infinitely preferable to a node 
that tries to shoot the other node when it can't ping it.

This way you can also start with a one-node cluster and do the induction 

Now all you need is to separate the monitors from services so you can 
easily monitor things the cluster didn't start (like that eth0 above), 
and it'll all start making sense.
