One my clients brought this plugin to my attention. Although running a multi-language site is a major undertaking, this plugin does a good job of simplifying the content management for a multi-language site. Some customization is required for other plugins and widgets to be integrated for full multi-language appearance, but if multi-language content is a hot item for your site, then this plugin may be worth a look.
