I wonder whether this project got anywhere since 2006?

João José Neto continued research (but I didn't seen he mentioned Newlisp in later materials.)

and contributed to Idea Group's Encyclopedia of Artificial Intelligence published in 2009. Google books have some preview of that book, including whole João's article.
