I think you are asking two questions.
#1 Is it possible to include a whole page in the PortletInclude Control?
[mark] No, that isn’t supported
#2 Is it possible to ‘signal’ the portlet that it is currently being “included”?
[mark] Yes, i would pass that as a parameter in the PortletInclude Control and expose a preference on the Included Portlet. That way, the included portlet can understand whether or not it is currently being included.
