Determine if user can progress workflow

I have been looking through various name spaces and cannot locate the proper place to determine if a user can progress an item through the next workflow step.  For example if I have a reviewer I would like to inform them up front which pages they can edit / publish without having to load the edit a page screen.  We have the user and the PageNode / guid of the page.

Hi James,

You need to check whether the user has permissions to work with the page

I believe that this is what you are looking for - permissions checking and demanding.
