I use TupleSpace and RingServer in multi-system monitoring  
application with self-configuring client daemons.  It will be  
released once I get it robust enough, maybe in a week.

The server starts up and creates a TupleSpace and announces it via a  
RingServer.

Monitoring daemons look for a RingServer and attach to the  
TupleSpace.  They register themselves with the server and wait on a  
Stream (implemented on top of the TupleSpace) for requests.  When  
they get a request, they run the indicated test and drop the result  
back on an output Stream.

The server reads the result Stream and puts it in the database.

This makes the monitoring daemons incredibly small and flexible.   
They have no configuration and no state.  All the hard work is done  
on the server.
