Jorrit is the leader of Crystal Space, which is another open source project like Planeshift, only its purpose is to build a 3d engine which can be used by games like ours. Many many projects are using his engine, including us. :-)
We are lucky because Jorrit believes that due to Planeshift\'s size and complexity, it is an excellent stress test for his engine. He assists us on almost a daily basis with the game and even customizes Crystal Space with features needed by PS.
So be nice to him. ;-)
