It's a bit misleading because tramp-minor-mode doesn't have any keybindings
so it's not a real minor-mode.  Also for dired, GUD buffer etc. this shows
nothing.

I think conditioning on (file-remote-p default-directory) was the right idea.

How about something like this for binding.el:

(defvar mode-line-remote-p
  (list (propertize
	 "%1R"
	 'help-echo (purecopy (lambda (window object point)
 				(format "%s"
					(save-selected-window
					  (select-window window)
					  (if (file-remote-p default-directory)
					      (concat "Remote: "
						      default-directory)
					    "")))))))
  "Mode-line flag to show if current buffer is for a remote machine.")

(make-variable-buffer-local 'mode-line-remote-p)

where mode-line-remote-p is added to the value of mode-line-format:

("%e"
 #("-" 0 1
   (help-echo "mouse-1: select (drag to resize), mouse-2 = C-x 1, mouse-3 = C-x 0"))
 mode-line-mule-info mode-line-modified mode-line-remote-p mode-line-frame-identification mode-line-buffer-identification...


And %R (not implemented yet) works a bit like %*: print R or hyphen depending
on whether (file-remote-p default-directory) is true or not.
