Adobe Forms - Workflow - EP

Hi,

I am doing some loude thinking. Currently working on a proposal to create an application with Adobe Forms. The idea is to have a workflow as well where the relevant party fills in their part of a form and so it moves to the next. The forms will be made available centrally via EP. I just like some suggestions on what would be the best way to have the workflow. There is a WAS (Java) available as well.
