I just came across with new JSR 286 WCM rendering portlet and thought of sharing here
Few of the benefits and features are.
1)You can attach Web Content Management sites and site areas to portal pages.
2)The JSR 286 Web Content Viewer does not need to be configured on Web content pages because it renders the default content attached to the page.
3)The portlet supports the portal Web 2.0 theme
4)Sessions are no longer required for rendering Web content for both anonymous and authenticated portal users.
For detailed article and list of complete features, have a look at
