Re: separate class that prepares an IteratorAggregate object for View layer - where to place this?

Well, you would not do it on the Behavior itself, since you want to pass
the object to the view.

Probably a static method as in your example that converts the find array
into an object that implements IteratorAggregate (probably 'app/lib' is
the best place for this).

Then in Controller::beforeRender you could iterate over the viewVars and
convert the arrays accordingly.
