I'm not quite sure whether your proposal is just rhetoric. In case you
mean it seriously: GVFS ought to have an nfs backend, called
gvfsd-nfs. See gvfs(7). But it doesn't seem to be installed by default,
at least Ubuntu's gvfs-backends package does not contain it. (It seems
to be distributed by Debian's gvfs-backends package, 'tho).

However, I don't believe it is necessary to use GVFS. Something like the
mock method in tramp-test.el, slightly adapted, would serve already, I
believe.

Sigh.
