Lars welcome back! As you might know already we have ported acs-workflow-4.3 [1] and everybody is impressed with your work -- check the #openacs chatlogs:
<ul>
<li><i>"workflow is the example to follow for documentation"</i>
<li><i>"acs-workflow is the best package we inherited from aD"</i>
</ul>
<p>
You'll notice that many packages are refactored to use worklows (e.g. etp). Anyway, I have something if you are interested which is both related to workflows and integration of services. I'll email you by the end of the week.
