More or less. You're want to do FooProxy more like:

  class FooProxy
    def initialize
      @foo = Foobar.new
    end
    def foo
      @foo.foo
    end
  end

However, most of the hard work of doiing this sort of thing has
actually been provided in Ruby through DelegateClass and
SimpleDelegate. You can find information on these in the Pickaxe
book.
