WHS RC1 is now available according to Tom. I vpn’ed into my home network to start the download off over lunchtime. I did find that the webpage said the dvd iso image is too large to download, but it looks like it will download if you click the download button regardless.
I’m looking forward to installing this software as several of my bugs have apparently been fixed. Not sure if I will get time to install tonight though, but watch this space.
