Workflow entity and State field

D7 work on workflow module

I think this way we should go with workflow in D7:
1) Workflow is entity
2) State is field
3) Core actions, triggers integration
3) State formatter is configurable for displaying within entity view states
4) Access to none-workflow entity to view/change could be optional
5) Rules, views integration

The http://drupal.org/project/statereference probably is good place to grow default views implementaion

Suppose workflows itself can exportable... with uuid integration...

Suppose for D8 workflow should replace|transform into node.(status, promote, sticky) as part of standard profile

EDIT: project is postponed
