Hi Don,
Assuming you want the workflow to be a proper petri net.
No, that doesn't really matter to us, except if there would be a real penalty of violating this condition...
Maybe you'd looking for the WF-GUI, put around the new "state machine" package (I don't want to call it workflow, even if that's the package name...).
I think we all should have a closer look at Lotus Notes and it's scripting capabilities and may Oracle WF or something similar. Ease of use if first, technology is second...
