As all you guys heard about the recently open sourced Terracotta, a JVM level clustering product, I was wondering if somebody in the Hibernate team thought about integrating Hibernate with Terracotta, maybe there's already some work undergoing into that direction.

My first thought was to build a trivial experimental 2'nd level cache implementation (even the HashtableCache would sufice for testing purposes) which would be distributed using Terracotta.

Is this idea feasible, or maybe you guys already have your own thoughts and/or eventually experiment already with some Hibernate/Terracotta ?

Can you guys underline some key issues that would need take care of when writing such a 2'nd level cache provider ?

Thanks,
Dorel
