It is possible to run the MacRuby runtime inside a pure Objective-C-based Cocoa app, which allows Objective-C to talk to Ruby objects (and vice-versa) inside the same process. Check out the MacRuby.h header file (an Objective-C API to talk to the runtime) inside the framework, or the EmbeddedMacRuby sample app.
