The Rossum Project (Robotics & Java)

I came accross something called the Rossum Project, and I thought some of you Java and Robotics enthusiasts would be interested in it. Their website is at http://rossum.sourceforge.net. They have a robot simulator written in Java. There seems to be some potential for collaboration between TinyVM/leJOS and the Rossum project.
Any ideas?
