Comment 8 for bug 609884

There's a patch for Nautilus on the opensolaris/sun site.
http://src.opensolaris.org/source/xref/jds/spec-files/branches/gnome-2-24/patches/nautilus-13-zfs-snapshot.diff

All the things specific for ZFS will have to be changed of course, but maybe this could be helpful, because one doesn't need to re-do the whole user-interface thing?
