I have worked out heuristic checks and the associated scored for
quorum disk to be put in. I have tried to work out on paper the
different scenarios that will play out and how the cluster membership
should work based on the eventual score. I think I can do away with
the GPRS modems for now but I will definitely integrate them in the
solution at a later stage.
