Thanks Raphael,

@Rusu,
A few reasons I wanted to use kinect_PCL; the application I want to build
requires some machine learning and computer vision algorithms (maybe
graphical models in future). But at the same time I want the application to
be based on a library/OS that has a potential to be widely used in future
(such as ROS). I tried the OpenNI interface and it looks pretty good. From
what you said, does it mean that the kinect packages in ROS will be replaced
by OpenNI libraries? If so, then I'll use ROS and OpenNI together for my
application. Let me know your opinion. 
I am still a beginner in ROS but as I develop my application I'll make
documentation and demos for using nodelets, PCL and kinect. I'd be more than
happy to contribute to a project like ROS.
Thank you.
