Yeah, it works really well. See

 http://people.freedesktop.org/~david/gvfs-connected-server-multiple-shadow-mounts.png

for the setup in [1]; here we have three mounts inside each other.

I've attached the patches to these bugs

 http://bugzilla.gnome.org/show_bug.cgi?id=555331 (gio)
 http://bugzilla.gnome.org/show_bug.cgi?id=555332 (gvfs)
 http://bugzilla.gnome.org/show_bug.cgi?id=555333 (nautilus)
 http://bugzilla.gnome.org/show_bug.cgi?id=555334 (gtk+)

These patches should be fine to commit as is; that is, I've tidied them
up, tested for locking problems and looked over them a few times. Works
fine on my box.

I think the UI rework in Nautilus can be done as a separate patch. 

Also, as a value-add (since you're buying not one, but four patches
here!), I've thrown in a new --monitor option to gvfs-mount(1) included
in the patch set! For free!
