Sorry, should have specified! As jballanc said, I was referring to MacRuby (http://macruby.org/). I'll add a link there for clarification.
RM and MR are both by Laurent Sansonetti, and the experience developing for them is identical. The Ruby code is just as portable as Objective-C between iOS and OS X. I'm working on something right now which uses both technologies and it's been a great experience.
