Using Flash, Flex or Silverlight is welcomed.
I need an application that is able to build a workflow (places, transitions and arcs).
The application is able to save the builded workflow in XML and post it to a given URL.
The application is able to receive the posted XML and rebuild the workflow.
We need to manage only places, transitions and arcs.
For places and transitions the application will be able to select users requested from a received XML.
XML knowledge is mandatory.
