mruby is making ruby more lua-like (embeddable, etc.). If this project does AOT compilation well, we might be able to shave lots of interpreter overhead from Ruby for some applications.
I say some applications because there are still people using Ruby to write non-web things, and I doubt if this project will ever support Rails in the short term
