Once I had to work remotely over 2g cell phone. Using remote terminal was too painful due to huge latencies approaching 1s. What worked surprisingly well was to work on a local copy of files in a local editor and then to run command remotely I would prefix them with a script that I aliased like rc. The script rsyncs first the tree to the remote host and then run the command there. These days for much simpler setup I use lsyncd to sync file trees and then the rc command just runs the command over ssh.

For that use case, if you have Emacs locally, you could use TRAMP - which basically works the way your script does. It allows you to transparently access files, directory structures, or even run shells on remote machines. It supports many protocols; the typical way it works, is it starts an ssh connection in the background, and uses the shell to ferry the file you want to edit to your local machine, and then transparently ship it back when you save.

  TRAMP does not work like that. First it does not have a whole directory tree, rather it just caches the opened buffers so things like grep etc. must run remotely which sucks on a high latency link or could be much slower if the server is not very powerful VM. Second at least like 5 years ago when the last time I played with TAMP it worked really badly on an unreliable connections or when the laptop switches to different wifi network. If ssh connection hangs, the whole GUI often hangs and sometimes after reconnecting I had to throw away resent edits and reopen the buffer. It could be that nowadays things are better, but for me nothing beats my lsyncd + explicit remote command script. Even file completion works with trivial efforts. As paths in my local tree copy matches the remote paths, completing by files just works, and it is trivial to call completion scripts for remote command from the completion script for rc.
