Python is a good language for workflow because of it's support for serialization of built in and custom types which is important for processes that need to survive a reboot. I think a good start to a web2py workflow engine would be an event model that let's developers subscribe to CRUD operations in the database and an API that provides a set of activities that do things such as create and assign tasks, wait for a field to change in the current item, send emails, alter permissions on the current item, delay, etc. Also, a workflow manager would be needed that dispatches the events, serializes/deserializes items and tracks their state so that if the machine is restarted, the workflow can be re-hydrated and resumed properly. I do a lot of Sharepoint workflow programming so these ideas borrow heavily from them but could probably be simplified and improved. I think web2py workflow engine would be a nice feature for businesses that use a lot of forms.
