WebCrypto might resolve the caption (and other text-file) issue, but what would
happen when the supplemental content was picture-in-picture sign-language
(which has previously been identified as an accessibility requirement -
http://www.w3.org/WAI/PF/media-a11y-reqs/#sign-translation)?

Recognizing the limitations of hardware (processing overhead), will user-agents
be able to decrypt streams that have been encrypted using 2 (or more) CDMs (aka
Glen's 2c scenario)? The current WORKSFORME response does not address this
question.
