Had a look at the links. The 2011 thread mentions problems that have been addressed by either nix-daemon or remote-build nodes.
There's also some references to socat but not much. Seems like forwarding could indeed be a solution but from what I read elsewhere it's a fragile setup and requires ssh-agent and passwordless keys. There's also some articles about using haproxy and nginx to proxy sockets but it's all very much ad-hoc. I'm also not sure how this would work given the security model of nix-daemon. The 2014 thread is also a good read but focused on using the cluster infrastructure to compile things. I don't want to go down that road yet. Perhaps in the future if necessary. At the moment I'd be happy with having nix-env and nix-shell on all machines. Is there currently any support for NIX_REMOTE specifying a connection to a daemon on a different host?
