I hate to ask a stupid question because it's probably in your docs somewhere, but could you humor my laziness and tell me if it's easy/hard to extend this at will? I think if you had some way for people to easily add the ruby counterpart of a bash command and then share them with others, this could really be nice. Beautiful idea either way. I like the idea of interacting with your OS the same way you would interact with irb or the lisp REPL.
