I’ve pretty much completed implementing the mechanisms in nautilus and gnome-settings-daemon to implement per workspace wallpapers. I’ve created a short video that shows the current state of the functionality:

As you can see the wallpaper is currently set for whichever workspace the appearance capplet is on.
I’ve put most of the patches (except the gnome-control-center one) into bugzilla:
gnome-desktop: http://bugzilla.gnome.org/show_bug.cgi?id=543596
http://bugzilla.gnome.org/show_bug.cgi?id=544241
gnome-settings-daemon: http://bugzilla.gnome.org/show_bug.cgi?id=544178
eel: http://bugzilla.gnome.org/show_bug.cgi?id=544223
nautilus: http://bugzilla.gnome.org/show_bug.cgi?id=544242
gnome-control-center patch is available here: http://git.jsharpe.net/ but is still a work in progress.
I’d appreciate feedback on the patches.
