Chamikara,
The code is available under branches/clustering.
Here are the changes I made to ClusterManager interface. Of course what I
did is just a prototype so feel free to experiment and change things.
public abstract void init (ConfigurationContext context);
public abstract void addContext (AbstractContext context);
public abstract void removeContext (AbstractContext context);
public abstract void updateState (AbstractContext context);
As you can the changes are where I replaced the add/remove/touch property
methods with a single updateState method.
I found it to be very cumbersome/expensive to intercept the property changes
and keep track of them on a per occurence basis.
Instead a single updateState method called at the end of the invocation
provides better alternative to handle the state changes. YMMV.
looking forward to your comments on the prototype.
Regards,
Rajith

Yes the implementation is build on top of the cluster manager.
I changed the method signatures slightly. But it's only a prototype.
I will not check it into the trunk, untill we run a successfull demo and
everybody is comfortable.
I will put that in a branch and then you guys can also make changes.
Regards,
Rajith

So nothing prevents your implementation from working on top of that.
