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

If you are doing this to enable people to remotely edit files you may want to look at 'tramp mode'
