TRAMP is one of Emacs' killer features. The ability to transparently edit files on remote machines, run shells, and use version control as if everything were local is remarkable. The implementation is impressively portable - it works over SSH, sudo, docker, and countless other methods by cleverly parsing shell command output.
I've been experimenting with an alternative approach that trades some of TRAMP's universality for speed improvements in the common SSH use case. This is very much an alpha project and nowhere near as battle-tested as TRAMP, but the early results are promising enough that I wanted to share it and get feedback.
