I've forwarded your proposal to Web and Broadcasting BG. I will ask the BG members whether the proposal satisfies their use cases or not.

This is based on a proposal from Netflix to address our requirements for secure binding of application protocol to devices, particularly on TVs, BluRay Players etc.

Note that the possibility for UAs to support pre-provisioned keys is agreed in the WebCrypto group. The issue at hand is whether there should be a standard way to expose a unique identifier associated with such keys.
> If you have comments or questions on the proposal please send them to the WebCrypto list, particularly if the proposal does or does not meet your requirements (public-webcrypto@w3.org if you are a member or public-webcrypto-comments@w3.org if not). This issue will be decided at the next WebCrypto call on 11/19.
