I'd just love to see this work well with a proper SCIP plugin on Windows. MIT/GNU Scheme sort of works on Windows, but you can't integrate it with EMACS. Dr. Racket comes closer, but the libraries have been moved from (or to, I don't remember off hand) Planet, and trying to get them installed is painful and prone to error. It becomes really difficult to study the lectures without a good environment and Dr. Racket is the most promising because it supports graphical output. I just wish it worked properly.
