I wonder, would it be possible to build a secure P2P client using encrypted Media Extensions and WebRTC? Going to check to see if EME supports encryption as well as decryption...<p><i>update</i> No. EME is only intended to be used by content consumers; even if it could be hacked to encrypt uploads &#x2F; outgoing transfers, that use case wouldn&#x27;t even be considered important as the spec evolves. Super lame.
