For example, the node with 0 arrival order might become a special kind of node.

As long as the root types are compatible, you can even name them when they're in different classes and field ... it will work seamlessly. Very cool stuff.

That makes it a ton easier to do stuff like this. Very minor point though: this way makes it possible to run clients on the cluster that don't all have the same code. Of course, that's not how most people use their clusters. :-) That’s awesome, thanks! That makes it a ton easier to do stuff like this.

Regarding discovering which nodes are in the cluster, you can now also use the plain Java cluster API we introduced with Terracotta 3.0. It makes your life a lot easier when doing cluster-aware operations. More info here: http://www.terracotta.org/web/display/docs/Cluster+Events Take care, Geert Hi Mike,
