Yep. My initial experiments in this direction suggested that getting it 
to compile and run with emscripten was Difficult. I didn't put very much 
effort into it though. I don't remember exactly where I got stuck, but 
the attached is a build script I was using to try to iterate closer and 
closer to an appropriately-configured and -compiled Racket.
