The database is used to store administered topics and queues,
persistent messages, durable subscriptions, and state information.
There are no plans to provide a memory-only server implementation.

That said, the next release will be deployed with a java based
JDBC database. I'm hoping a stable release of axion
(http://axion.tigris.org)
will be available for this. If not, we'll use hsqldb (http://hsqldb.sf.net).
