Interesting. Some years ago I’ve relied on SSHFS to have a decent speed when operating on remote files. I wonder if this might have been a solution as well.

Well, there goes one of my predictions 😒 I was convinced such a “Tramp, but using an ad-hoc server one the remote side” would use a server written in Perl (in my original prediction, 20 years ago), then revised to Python. I think I would have counted partial points for one based on Scheme or Tcl, but I definitely did not foresee Rust coming.
