Hello Thomas!
What I'm almost missing is a good WCMS in the Ecosystem of GateIn. In fact eXo WCMS uses Oracle's JDK proprietary API. So in fact you couldn't deploy it on on IBM Blades (with PPC) or on Platforms like FreeBSD. On FreeBSD my prefered Platform, Jboss 5.1 and GateIn 3.2 runs perfect with OpenJDK6 only. The official Diablo Caffe JDK 1.6.0-7 has issues with IPv6. And a fix will breaks the licence with Oracle.
Here in my enviroment is no pleace for Oracle's proprietary stuff. Oracle JDK is the best, but it produces always problems with the licence.
