More than clustering, does this approach also enable a new PM-based 
implementation of the Model 3 deployment, ie a remote, shareable PM, 
accessible from various Jackrabbit instances ? I know this is not the 
purpose of a PM, but with this proposed architecture, results are 
functionnally the same, aren't they ?
I also guess that this approach will be way faster than the RMI one, 
even if it's not its primary goal.
