Hi Caleb, did you have a look in the ChangeProcessInstanceVersionCommand? I haven't read thorugh your blog completly, but at least it tries to solve the same problem. maybe not that sophisticated yet. And a hint: It may get hard to commit such functionality in jbpm 3 by now, since it is switched to "maintenance mode", because new development effort goes in jbpm 4.
