[racket] Try Racket

This is great, but it really needs some security improvements.
(file->string "/etc/passwd") works fine, as does

I know it seems really perverse to create a web-based service and then run it all client-side, but it looks to me like this might be the easiest path to distributing the workload. My recollection is that in the past, it's been hard for Windows users to run apps that serve web pages locally, but perhaps things are easier now.
