Re: ACTION-40: Propose text for bug 17202 to propose how to share keys without leakage of information

The sharing of keys for performance may apply in multiple cases. This proposal also impacts bug 21855.

Keys may be shared between multiple sites which have a trust relationship. For example a sports network may own multiple sites each dedicated to different sport content. That content may all be tied to a single “network” key used to derive the content keys for individual streams. Any consortium of media sites may have a relationship which allows them to display each others content. In this case, an active key acquired for one site should not need to be re-acquired for another.
