Rails mountable CMS and or Blog engine

I am looking for a mountable CMS engine that I can attach to my rails 3 app. I would like to do something like:

MyApp::Application.routes.draw do
  mount Resque::Server, :at => "/resque"             # This already exists and is awesome
  mount SomeAwesomeCMS::Server, :at => '/docs'
  mount SomeAwesomeBlog::Server, :at => '/blog'
end

Anyone have any positive experiences?

Thanks
