Embedded Database Replication

As we all know, embedded databases out perform server databases on every occasion. The problem with embedded databases is that theyre difficult to scale. If I were to create an entire enterprise web application within a single jar file using embedded tomcat and embedded objectdb I would run into problems trying to cluster the data.
