This is what I keep trying to get at - adaptivity is _not_ the only
benefit of having greater client control over the stream with chunked
requests, whether they be physically separate files or a single file
with byte range requests.

Greater control over buffer readahead and the ability to separately
address segments of the video are also big benefits.  I'd go so far as
to say that those benefits are more important to us and can have more
positive impact on the user experience than adaptivity.
