Their distribution is called Helios and is based on OmniOS. I think they were supposed to make it more suitable for consumer use / home install at some point - the package repository is public if you want to try to cobble it together on your own.
It's still private. I believe this is a case of "just gotta open it," but that takes some work (and I am not sure, I don't know all the details yet, I could be wrong). I have it on my to-do list to try and investigate this and get it done sometime soon, we'll see.
