I happened across Jukka Zitting's web page in which he announced some of the 
new features in Jackrabbit 1.4.  In particular, this paragraph was of interest.

"Service provider interface for JCR. The jackrabbit-spi component defines an 
architectural layer below the JCR API. The SPI layer is designed specifically 
for remote access and outlines a way for us to avoid the performance 
limitations of JCR-RMI that works on top of JCR."

This is because I have JCR client applications which are currently accessing 
the JCR via JCR-RMI.  With a significant amount of client side caching the 
performance is acceptable for our current usage... but only just.  The prospect 
of accessing the JCR external to that JCR's JVM in a reasonably performant 
fashion is very exciting.

Looking at the mailing list I can see references to a method of getting remote 
access to a JCR using SPI and RMI.

Marcel mentioned the following alternative:
jcr2spi<->spi-rmi<->spi2jcr<->jackrabbit-core 

Thus far I have been unable to find any How to, Readme or wiki page which 
covers this particular configuration.  Can someone point me in the right 
direction?  Is there another configuration I should consider first?
