You also have to consider the case when a clustered system is in 
operation. Then, they are likely to need to share data that is 
installed, and a sensible back-end may need to synchronize such writes 
across a number of nodes/clusters.

I agree for a single-server environment, having an in-memory cache will 
be the fastest, but having a switchable JNDI server will allow both :-)
