I'm very interested in this as well. I hope to work on it this winter, when I spend my free time on legos and computers instead of boating and playing sports.

You might consider getting a trademark so that not even lego can say anything to us about the name. Is this an expensive prospect? How about a superfund for it? Probably would want to get it in the names of all the major authors. Frank (22 years ago, 20-Jul-02, to lugnet.robotics.rcx.legos)
