Robert - 

Have a serious look at Spread (http://www.spread.org).  There's a 
Python module for it on python.org, and I believe the Java 
interface is included with the code from spread.org.  I've not 
used Spread from Java, but I have a bunch of different Python 
processes on half a dozen or so machines (Both Linux and Win2k), 
all communicating via spread.  It's quite simple to use.

The spread server daemon has been up since I started it, way back 
when the first Python spread module came up.  It's stability is, 
so far, as good as the linux box upon which it runs.

HTH, 

Bill
