Assuming you're thinking of DRM, are there any related use cases other than
crypto?  Encryption for DRM, at least, isn't a very compelling use case;
client-side Javascript encryption is a very weak level of protection
(putting aside, for now, the question of whether the web can or should be
attempting to handle DRM in the first place).  If it's not DRM you're
thinking of, can you clarify?
