Renjin - R interpreter written in Java

Today, I stumbled upon a web page under the Google Project Hosting, which is a re-implementation of R in Java. It is a good news for R & Java programmers because it opens a new way to call R functions from Java directly. Project is open source and distributed under the GNU GPL v3. Many functions were implemented, R interpreter works well. I think there is much more work to do, especially, speed is the main issue. Unfortunately, there are only three developers that i only saw and this is a wonderful work. Finally, it would be good to be involved this project. The project web page is http://code.google.com/p/renjin/ and there is a live demo of the interpreter in site http://renjindemo.appspot.com/.
