Thanks for the response..

I shouldn't have mentioned persistence..I don't want to use database.. my
bad.

I understand that i can feed events to all the servers in the cluster and
maintain working memory.. is there any other way ?
Can i replicate the working memory as i would replicate a regular cache ?
Can i replicate it incrementally when the facts are asserted (not the entire
session each time, only the delta) ?

My goal is to achieve failover and high availability using cache replication
across cluster.
Feeding each event to all the servers is my last bet. 
I don't know if an event affects the facts until the rules are fired, so i
cant filter them before they hit the servers.
