Not sure how many people here know of or use Windows Home Server, but if you do Microsoft recently announced they are pulling the Drive Extender technology from the next beta of "Vail". Just today HP, one of the first hardware manufacturers of Home Server hardware, announced they are no longer making or selling their Media Smart servers.
Just thought I'd share this info with those who use the product, if you didn't already know. WHS is an awesome platform, I've used it since beta and it has saved my butt quite a few times.
