If you take a good look at the list, you'll notice that OpenDS is missing.
FYI, there is a commercial version of OpenDS - Sun OpenDS Standard Edition.
From what I know, Oracle is still defining the strategy for OpenDS. Until then, we do not know what will happen to OpenDS.
A lot of development work has been poured into OpenDS. It's a total rewrite in Java from Sun Java System Directory Server. I'm keeping my fingers crossed.
By the way, Directory Service is another strength of us. So we'll be watching closely on the development of OpenDS.
