+1. 
Would it be worth making this pluggable? I.e. the user to plug he's own code to determine on which level the node is.  Might be useful in some environments where nodes are started on demand and user cannot configure the level through config. I'm thinking about clouds :)
 (with a default)

>>> In order to complete ISPN-180 lets agree on a definition of collocated nodes. So, when are two nodes collocated? It depends on what we have defined as additional metadata node input (i.e machineId, rackId, and/or siteId). If we have defined only machineIds then the answer is obvious. However, if we have defined machineId, rackId, and/or siteId for all nodes is it then that the non-collocated nodes are the ones having different siteId? In another worlds if nodes have different machineId and rackId but the same siteId are they collocated?
