This is the future. Systems like Isilon running Windows 8 and providing storage like this will be defacto before long. In Windows environments at least.
Really believe that if EMC/Isilon gets on board with a OneFS and Windows 8 offering it will make 2 better products than currently exist. EMC/Isilon recently purchased LikeWise to help with AD integration, but it will never be Windows 8 native integration.
There are some other vendors working on Windows 8 clustering Isilon style but NDE binds me from talking about it. Be sure you will see this idea released this year from a few vendors.
