I did test it locally (Emacs 22.1.50.2, Tramp 2.0.56). If the remote
file name in .recentf contains already an absolute local file name,
expand-file-name does NOT open a connection. The connection is opened by
file-readable-p.

The remote connection is NOT opened with the following settings in my
.emacs:

(require 'recentf)
(add-to-list 'recentf-keep 'file-remote-p)
(recentf-mode 1)

Yes. But it seems all file names in .recentf are already absolute; at
least according to my tests. So the settings above might be sufficient,
aren't they?
