First of all, congratulations for this beautiful piece of code.

Recently, I have been using it in my daily work with Emacs + Org-mode to create "literate scripts". I would also like to propose my colleagues to use it but they feel Emacs as a real obstacle. They are more receptive to Jupyter, though.

So, trying to connect the dots, I found a Racket kernel for Jupyter (iRacket). However, I have not been able to create Jupyter cells that make use of the Rash reader on it. Would it be possible?
