Well, if you must - you must. 
But we shouldn't have the core depend on the clustering, just add the 
minimal stuff that you need in the session. 

If we can stop the hacks and clean something - I think 5.0 is the best 

I would preffer to have a consistent hook mechanism for everything - 
I'm not sure what callbacks will be involved in the clustering.

Bloat is not about MB or storage. It's about code complexity, potential
security, etc.

That's what I was thinking about - a set of jars and minimal configuration.
Eventually using only MBeans for configuration and setup.

BTW, we could use MBeans for the optional packages too. I think it works
pretty well. We'll need to get a consensus on requiring JMX for tomcat5,
but so far it doesn't seem it'll have a big impact on the code ( I did
all kind of experiments with modeler and ant lately ).
