For back/front you can place the object behind others, then enable
XRay option to draw over the top, aside from that - your
Empty-image uses object alpha, no trickery there.

Activate/de-activate - just use a layer, or object hiding from outliner.

as for properties shelf and movie clip - your right :S

Yes, but it would make object drawing code even more convoluted and
dont think its likely the feature gets added just for image backdrops.

Even if this is done I think we stall have issue as who stores the
data - window vs object... and how they reference eachother, and how
this is made manageable by the user in a not-annoying away.

This is possible - the bacground image could point to an object for
its placement, though it doesn't resolve the limitation that currently
background images are window data (not apart of the scene)

Normally with this stuff its possible - just trade-offs with the
complexity and having to manage all these draw modes together + draw
passes (we already do for XRay - but adding an always draw-behind may
need another pass for eg).
