To set the record straight:

1) Rubinius is BSD licensed.
2) There is a mixup in terminology here. We are not recoding the
standard library (stdlib). We are recoding the core library. The core
library is all methods on Array, Hash, String, etc. everything that is
available in ruby without a require. All of that code in MRI is in C,
and 95% of ours is in ruby.
3) I'd love to see IronRuby using our core library rather than
recoding it themselves. The JRuby guys and I have talked about that
very thing.
