I don't think it is. The talk was a year ago and it still isn't available.

I created my own version, based on (I think they did that too) on NixOS modules system.

But I'm wondering how it compares.

Actually looking at https://gist.github.com/burke/72ca46c80e57a25907a75611ee5eb6... I think their goal is slightly different than mine.

There's also https://github.com/hercules-ci/project.nix but it wasn't touched for a year now.
