Now I have a shell script `rcargo` which remote compiles rust crates: I work on my laptop but have beefy machines on my home and work LANs. You'd have to reimplement cargo to do it much finer-grained, apparently: sccache used to and gave up?

The real trick is ssh's ControlPath config var, which allows shared connection for much-improved speed: ChatGPT taught me this one!

The other option is Nix, but I'm not *that* bored!
