The Virgin.com redesign sports a header that provides a boatload of functionality using mega fly out menus: locale selection, micro-site navigation, registration, login, and newsletter signup. I like that they make these options readily available wherever you are on the site. The longer drop downs like the registration form, for example, seem a little long for users on smaller screens, e.g. netbooks.
