That's a very interesting idea. It would be useful in other situations
needing multiple LODs as well.
For completely selfish reasons my first thought is in games; embedded
videos could be streamed at low res until a player gets close, upon
which the high res data is added. This saves having to either stream
and decode high res all the time, or do an expensive (in performance
terms) stream disconnect/reconnect to switch qualities.
I could see it being used in other places too, such as YouTube's
multiple resolutions. Instead of having to discard everything that's
been cached on a resolution change, the viewer could just start
downloading the higher res data to add to it.
