Hi Glenn,

As far as I can recall, this might be an open issue for mobile delivery
(both iOS as well as Android and possibly others). I believe the issue is in
managing 2 data-streams concurrently on the mobile devices (bandwidth and
processing), which hand off video to the native video players on the
hand-helds, and do not use the web browser like on the desktop experience.

I am unaware of a proposed solution at this time short of burned-in
captions, coupled with some server-side sniffing (or maybe media-queries?)
to deliver the correct media file to the hand-held device(s) - but happy to
be schooled otherwise.
