This is some great news, one of my biggest criticism of SharePoint has always been the fact that you need a Server to run it on, even just for development. I’ve managed to work around this with lots of ram a collection of VPC’s with diff disks. But it looks like it’s been solved here. I’m going to be trying this out this afternoon. The next question will be if the Visual Studio WSS Extensions work with it, as they won’t install on a machine where it doesn’t detect SharePoint installed.
