Thanks for your reply. At this point I think I need to connect the two projects to explore further. You've already expressed a willingness to help, so I'll put the ball in their court and encourage them to come here. If you want to follow up yourself you can find more about the project in question at http://www.wf4ever-project.org/ (let me know if you want any introductions). The discussion that led to this was actually in another project (called DataFlow), but I'll not confuse things by introducing that project yet (I work on it myself and am evaluating opportunities).
