I think the responses you have heard so far talk about replication to provide availability (HA-JDBC, the ongoing Derby effort).
What you are talking about is basically using Derby as a reliable front-end cache to a back-end database where the connection can be unavailable from time to time. What this is about is really synchronization, not replication. Synchronization is keeping two sometimes disconnected databases in synch. One product out there that works with Derby is Daffodil Replicator, see http://sourceforge.net/projects/daffodilreplica/. It's an open source project using the GPL license.
