Donavon West has posted example code to put together a pre-execution environment for the WHS Console to allow developers to test their Add-Ins against various Cultures. This means you can test localized versions of an Add-In without having to install a fully localized copy of Windows Home Server.
This is of little use for the casual user as the actual console itself (or at least Microsoft's portion) is still in English, but Add-In developers should find this extremely useful. The reason I wrote the loader was that I needed a way to test my twitter Add-In @WHSTweet as I have it translated into German, French and Spanish.
