While living in India I made a little prototype for a process-flow based system for lawyers. Its a Java SWT/JFace app, using the Eclipse Graphical Editing Framework. I love GEF. It boggles my scrotum. Anyway, its not much, but I'm not working on this anymore and so I've decided to set it free. Someone with more legal expertise and more devotion than myself could create something very cool along these lines, and probably will, someday.
