I believe this is a very good news for all that are trying or using portal/portlet. MyVietnam is porting its mvnForum product to portlet and has tested and made sure it run well on IBM Websphere Portal, Liferay, Exo, uPortal, Jetspeed2, StringBeans, pluto. We are in the process of testing and integrating with Oracle Portal and WebLogic Portal before we make a public annoucement of the General Available 1.0 version.
More over, MyVietnam also provides mvnCMS portlet, which is a both content management system and online news publishing system. This mvnCMS portlet also run well on IBM Websphere, Liferay, Exo, uPortal, Jetspeed2, StringBeans, pluto.
With mvnCMS, you can build news publishing sites such as http://www.bbc.com
mvnForum and mvnCMS are tightly integrated into MVN Collaboration Suite and available in 2 edition: standalone edition and portlet edition.
I think besides the inter-portlet communication, the other very important is a public API to deal with user database and permission database of the portal. This is because portlet does not manage this so portal should provide a public API to access it. Currently we have to use vendor's API but it will not compatible with other portals.
Other things is portlet should be provided IP and UserAgent whenever possible, because the portlet usually need IP and User Agent information to decide what should be processed.
When the specs Portlet 2.0 released, mvnForum and mvnCMS will be updated shortly and we will provide version for Portlet 2.0
