doing hayzoos' job :P

presenter_example.rb

class Vid < AR::Base
  after_save :encode

  private
  def encode
    VidEncoder.go(self)
  end
end

class VidEncoder
  include Rails.application.routes.url_helpers

  # default_url_options should be set by server setup or
  # a setup block in your test system

  class < self
    def go(obj)
      Zencoder.stuff(:source_url => url_for(obj))
    end
  end
end

I know how to set it for an individual class - I've done that, successfully. But I should be able to set that somewhere for the entire application - so I don't have to have multiple lines like

config.action_mailer.default_url_options = ...
ZencoderCommunicator.default_url_options = ...

That's bullshit, when they're all the same setting. I need something like

config.default_url_options = ...

The others can override that value, if need be.
