The logic was - he's gone down the JBoss route, and might want to use JBoss replication, but on reflection, it's probably wrong to assume that it's faster to get into JBoss replication than Terracotta - point well made.

Is there any particular reason why you think Terracotta won't be useful?  On
the face of it, it seems like the perfect solution, but I may be
misunderstanding the issues involved.

In the Terracotta kit, there's a DWR-based demo that uses Spring beans to
distribute state for DWR objects across the cluster.
