Hi Aaron,

Good to hear from you.

We have added basic clustering capabilities using Hazelcast. JACOB now uses
JSON serialization with JACKSON. Both these feature are on the trunk and
will be coming in 1.4.

We can definitely discuss improving the engine. I am game to make ODE more
modular in design, reactive and scalable keeping in mind a migration path.
