I'm not sure I fully understand your question. Within Zope and given
that you've installed the ZEditingContextSessioning product, you'll be
able to get the session's editing context with:
  REQUEST.SESSION.defaultEditingContext().

  There no other impact on traditional zope mechanisms: values in forms
  are passed to your methods as parameters and/or in REQUEST, and you
  can use the objects you get from e.g. ec.fetch() to populate the ZPT
  a method returns back.

Last, you can decide if you want to control when sessions' ec save
their changes, or if you want them to save their changes automatically
after each request/response loop by setting the special parameter
'bind_saveChanges_to_zope_transactions', cf.
   http://modeling.sf.net/UserGuide/framework-integration-zope-options.html

        Hope this helps,
