Using Emacs server and emacsclient on other machines as other users

Question

I know that after I call (start-server) inside an existing Emacs session I can then use emacsclient -c (on the same computer) to create new frames

Answer 1

Aaron Gallagher implemented a solution: http://blog.habnab.it/blog/2013/06/25/emacsclient-and-tramp/

It works (AFAIU) like:

• emacs server is started with tcp
• He opens a connection to a remote system with tramp-sh, opening a forward port ("back channel")
• tramp-sh is advised to copy an extended auth cookie file to the remote system
• On the remote system he calls a special emacsclient.sh shell script that emulates emacsclient but prefixes the file names with the corresponding tramp prefix that is found in the extended auth cookie

I've added a comment to his blog post proposing this idea to be discussed and enhanced on emacs-devel.
