This June, we will be releasing our new web script infrastructure and set of AJAX-enabled (read: snazzy and usable) portlets for DM and WCM. These will be tested and certified with both JBoss and Liferay.
I'd recommend evaling base Alfresco content services, including our XForms support, staging, and deployment support, and then adding an eval of our upcoming 2.1 portlets when we release in a new Community build in a few weeks time.
