When I asked my question about the 1 gig software, here is one interesting answer I got (in the interest of confidentiality, I will keep their identity secret). One of those that I know about is Orion. It is seriously lacking in documentation or comprehensive examples. It is more like a hotel room without a key than one without bath bubbles. At least with tomcat, jboss, JOnAS and the other open source ones, you have active user groups and can always look at the source and make your own room key.
