   All of this discussion has been so interesting that I almost hate to mention
   that I was not thinking of a caching situation at all. I was thinking of a
   situation where the user has consciously downloaded the resource for more or
   less permanent local storage. People often download large documents from
   Internet servers so they don't have to endure the download delay every time
   they want to look at them. They often download interesting news articles
   from Web sites because they may disappear from the server after a few days.
   They often record TV shows to add to their video collection.

In many cases, a downloaded version would work just fine.

However, if there is any low-level synchrnonization between the
content and the material, a different version might be different
enough that it would not be able to synchonize.

Even at the high level, commercial breaks can vary from one showing to
another.

Hence, I suspect that the broadcaster would, in many cases, wish to
preclude use of pre-downloaded content.

Of course, the broadcaster might want to allow such, in which case the
mechanisms should operate on both the live and downloaded versions
equally well.
