[rules-users] Shared Facts across nodes

[Mauricio Salatino]

Hi Mauro,
At this moment you can't share the session state between multiple nodes.
You can replicate your sessions in different nodes. Which means that two or
more nodes will contain the same set of facts.

Drools Grid was an experiment, so I don't recommend you going on that
direction.
