We have a Java API for Spread that you mint be interested :)

I'm working on a research project where we need a generic service and  
API for group communication, so we built the jGCS, a Group  
Communication Service for Java.
This service uses a generic API and has several implementations.  
Spread is one of them. One of the good features about this service is  
that one can change the toolkit that provides group communication  
without changing the application code, using the Inversion of Control  
design pattern.

Regarding the Spread binding of jGCS, we noticed that the Spread Java  
API is a bottleneck in performance, so we implemented jGCS using the  
jGCS is a very optimized Java API alternative for Spread.

You can find more information about jGCS here: http://jgcs.sf.net
and the project: http://gorda.di.uminho.pt/
