Further to my previous e-mail:  I've got curious and tried it out, and it works fine.

- Install correct emacsclient on remote.  (version 23 works OK for Aquamacs 2.x and 3.x).  Test with "emacsclient --version".

- Install editor script on remote as per blog bost.  Don't forget chmod +x aqclient

- Install SSH command script on local machine, as below (I had to adapt the paths so that it would go through Aquamacs.)  Don't forget chmod +x aqssh

- (setq server-use-tcp t) and (server-start) on local Aquamacs instance.  Can be put in your Preferences.el.

Then call "aqssh  remotemachinename" to establish connection, and when you need to edit, call "aqssh".

Works for me.  When doing "sudo", you need the root account password on the remote for obvious reasons.  The script could, of course, work around that.  Tramp is sort of slow for me.

Script follows below.
