Back in the day I had some dealings with Joyent, and I pitched them on Nix for SmartOS. I couldn't get them to take me seriously, because they were old-school Unix heads, but damn that would have been a great system. Define a zone with a Nix derivation, the Nix Daemon installs all its dependencies into a shared Nix store, which then gets mounted read-only into all the zones. It would have eliminated all the copying things around they were doing with pkgsrc, speculatively installing a bunch of stuff in case you need it, Manta etc. Alas!
