The question is whether this would suffice (sharing and revalidating the
state items among shareditemstatemanagers)or more things are needed to
ensure integrity.
as long as you can ensure that a cluster node does not store changes
that conflict with another concurrently running store operation on
another cluster node you should be fine. as I mentioned before I think
you have to use some sort of distributed locking on the level of the
different SharedISM in the cluster to ensure consistency. e.g. some sort
of a distributed variant of the read-write lock in the SharedISM.
