ariels@jpmens @ed1conf ed needs an add-on such as mountpoint-s3 [1] to do this. Working on a way to do this using #emacs_tramp, which comes built into #emacs. This may settle the #editorWar s.
HaraldEmacs has a great feature of editing files through an ssh connection: tramp.
I haven't used it for long. And in the time between, to make it more obvious that this is a remote machine, ended the prompt with the character "❱". We have Unicode, use it.
Which hangs tramp. Which hangs Emacs and needs C-g to get out. Not nice.
The solution was simple: add the character to the tramp-shell-prompt-pattern customization.
BUT: hang? I would rather be called names, really!
