I think Jason van Zyl was originally planning on doing it, and I was
hoping to assist.  As far as I know, thus far, nothing has been done.

Personally, I think all workflow engines should be rule-based to some
extent.  Else, you're not really doing decisions/action trees

Then again, I don't know what ECA is.  What's ECA?

As far as references, there are several commercial vendors,
all of which use rules somewhow:

        cysive.com (Their cymbio platform has a simple rules-engine
        that doesn't take advantage of RETE).

        savvion.com (I think they have a true RETE engine in the
        background).

Over at jakarta.apache.org, there's a Workflow component, but
I think it's more UI-Workflow, as opposed to process-workflow,
but I could be wrong.  Craig McClanahan (sp?) is leading that
project, I do believe.  Check the jakarta-commons mail archive
for information.
