he's talking about the flexible processes, where rules can control the execution of processes. It's a feature we have, that not many people are aware of - it's not ready for prime time use, still incubator. Krisv will respond in a bit, with some pointers.

What you should do when you want to introduce a "wait point" is to do the merge of you current flow with one of this Conditional Start Event using an Converging Parallel Gateway. The gateway will not continue its execution until all of its branches get executed.

The good thing about this solution is that is easy to create your own task definition to put in the editor palette and that you can create a single work item handler and reuse it for all your 'wait points'.
