Here she is, best of both approaches!

module Translator

  module ClassMethods
    attr_reader :translations

    def translate(from_word, options)
      @translations ||= Hash.new
      @translations[from_word] = options[:to]
    end
  end

  def self.included(receiver)
    receiver.extend(ClassMethods)
  end

  def translations
    self.class.translations
  end

  class Base
    include Translator
  end

end

class NewTranslator < Translator::Base

   translate 'customer_profile_id', :to => 'customerProfileId'

end

p NewTranslator.new.translations

I feel a little odd putting the class Base declaration at the end of the 
module, but if it's not there it has to be outside it entirely (and it 
must still occur _after_ the code inside the module), something I don't 
really want to do.

Anywho, thanks again for the awesome help. You guys rock!
