I m working with EhCache for Hibernate and for application level cache since 3 years ago. We use it with RMI for cache invalidation and it works really good. If you use the cache for replication you should take care about the object graph, it could turn very heavy with high cardinality relations.
If you use EhCache for Hibernate you could use it for Query cache (it s a good improvement for read-only tables) and it the table is modified it cleans the cache automatically. Using EhCache to cache collections is a good idea too, to avoid joins a sub-selects.
