[Zope] more workflow products ?

[Uwe Chalupka]

Hi There !

Does anybody know some more workflow products than DCWorkflow of CMF, 
OpenFlow or OOPServer ? They are not really appropriate to my 
intentions. I'm searching something working near to the base of Zope, 
sufficient for a really simple Workflow (with only one or two 
controlling instances for example).
I don't only want to handle content, but also handle object changes in 
the ZODB within the workflow, that's my problem.

I am thankful for every further product tipp told to me.
