I was more concerned that chunked files are easier to decode and
manage over the network. If you think it won't be a problem from a
browser implementer's POV, then that's fine. I have thus far only
heard from browser vendors that synchronizing independent streams is
really hard and they won't do that at any time in the near future.
Even Apple who already have a working implementation of adaptive HTTP
streaming, were reluctant to do any synchronisation of separate
resources in the browser. So, maybe you are saying it's now time to
take that step?
