I'm not familiar with Jython, but providing a BSF compatible interpreter 
would have certain benefits; primarily, that many existing applications could 
automatically plug the Ruby interpreter into themselves.

Is (2) a Ruby-to-Java translator?  And, by (1), I'm assuming you mean that 
you could do all of the following:

1)	String result = ruby.Ruby.eval( " %w{a b c d e f}.find{|n| n == 'c'} " );
	// => "c"
2)	$ java -cp ruby.jar irb.rb
	irb(main):001:0> p "Hello World"
	"Hello World"
	nil
	irb(main):002:0>
3)	String result = (new ruby.Regex("/(.)(.)(.)/")).match("abc")[2];
	System.out.println( result ); // => "b"

I'm sure the last would be useful, although you'd lose most of the Ruby good 
stuff.
