Ha, I guess you're right. When I type /sudo:: at the prompt, ido tells me the next completion is "localhost:", but if I ignore that and just enter my path, it works fine -- only one password prompt. I guess I thought ido was showing me something important about tramp internals, something I didn't know before, but maybe it wasn't really that helpful… Thanks! -- GNU Emacs 24.1.50.3 (i686-pc-linux-gnu, GTK+ Version 2.24.10) of 2012-05-01 on pellet
