I recently received a grant from the Salesforce.com Foundation for approximately $15,000 annually, indefinitely extendible. I have been using the software provided to explore the intergration and ease-of-use potential of software services on demand and how they provide workflow capacity to businesses.
I have also been developing and experimenting with open-source workflow tools including the Galaxia workflow tool and the workflow module in Drupal. None has particularly impressed me as well-done yet, even the more complex ones that enable full flow modeling, simulation, and optimization
