I think Thomas is referring to the proposal to simply concatenate the
different bandwidth alternatives into one file to make access and
loading faster. I don't think Thomas is suggesting that to necessarily
mean that the files of one bandwidth need to be chunked.

I actually agree with Thomas - I think we need to keep the different
bandwidth alternatives as different files. But I would also say that
if we can avoid chunking within a single bandwidth and can find means
of switching mid-stream, that would be nicer.

Right now, the chunking on MPEG is used to allow for live streaming,
too, because it updates the "file size" regularly. But I don't think
that's absolutely necessary to enable live streaming over HTTP.

Cheers,
Silvia.
