WorkflowCommander here. You can make use of the ApplicationInterface API functionality in Powershell. My Powershell module is featuring more than 20 cleartext Cmdlets that allow you to do basic tasks like duplicating objects, importing / exporting objects from / to XML and so on.
It's easy to implement and extend. So if you're interested get in touch with me and I can send you a factsheet or arrange a live presentation.
