XRuby: Another Approach to Ruby on the JVM

It's different in that it's a Ruby to Java bytecode compiler, whereas JRuby currently uses an AST-based interpreter, together with some JIT compilation. InfoQ caught up the XRuby developers for a status report, and invited the JRuby team to offer their opinions on cooperation opportunities.
