Guss you will need to provide more details for people to offer comments. But I have two initial ones here: 1. Check into passivation feature in JBC.

Maybe thefine-grained replication and distributed object graph can help out. -Ben View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3958646#...
