This it the Release Candidate of the up coming 2008.11 version of OpenSolaris.
"From dorm room to boardroom. OpenSolaris has everything you need to take your brilliant idea, build a prototype, test it, deploy it, and run it on production servers -- out of a loft, or across your enterprise. And when your application goes viral, you won't have to throw hardware at the problem, or switch to a different OS."
OpenSolaris uses the Gnome desktop which allows for simplified interaction with the operating system.
