We now have in beta testing the ability to detect whether the user is accessing your site from a mobile phone and, if so, redirect them to a different set of pages.
This approach allows you to build an entirely separate set of pages for mobile browsers. If your content is organized in the database, you can access a different slice of the content for mobile users, without having the re-enter anything. You can also use our automatically generated image renditions to deliver mobile browsers smaller images.
If you would like to participate in the beta test of this feature, please contact us.
