-If a node fails, it should transparently be redeployed on a different node. So actors imho are homeless.. they run

-- It should be transparent which node starts/stops the cluster. Perhaps some kind of 'before the world starts' and
-'after the world ended' logic could be added. The consequence is that there are mixed responsibilities in a node.
-
-- A node has the mixed responsibity of being part of the grid and doing checks. It would be nice if one could create
-cluster nodes very easily (just spawn a jvm and everything will be copied on them) and if one could create 'client nodes'
-that communicate with the grid and do their validations.
-
-- Each node has been expressed in code, so it is very hard to either use a large number of nodes (lots of code) of to change
-the number of nodes without changes all the code. It would be nice if one could say: I want 100 jvm instances with this
-specification.
