I never really tried to use NSArrayController in MacRuby, but I know  
that Rich uses it in HotCocoa and it seems to work well. And it's  
certainly possible to use bindings in MacRuby.

Could you upload your code somewhere so that we can have a look at it?

Also, it's great that you're converting the book exercises to MacRuby.  
If you are willing to contribute them after, I would be glad to  
package them in the distribution :-)
