Since we now have Double Ratchet (Signal,Omemo, Wire) it would be great when this could be applied to group video/audio conferences maybe with agreed keys per session/conference.
In messaging each message has separate key and it is TCP, now it is UDP and we need ZRTP/SRTP for groups. I think Wire supports group encryped audio/video.
@dev_ponies There's still the other problem, that Matrix's encrypted messages contain a Matrix message, not an XMPP message. So the XMPP recipient's client would have to either be able to interpret and send Matrix-style messages in the client, or the Matrix client would have to be able to interpret and send XMPP-style messages
@dev_ponies Because no server in between can read and rewrite the encrypted blob to be suitable for Matrix or XMPP clients, the client that receives and decrypts the message just won't be able to understand the data that it contains if it was sent by a client of the other protocol
@stevenroose no, but it somewhat defeats the point of Matrix: you’d end up with that server being the single point of failure for everyone participating in that MUC (ignoring FMUC and MIX?), just as the new bridge (which uses prosody to talk s2s xmpp) is today. So might as well stick with bridges, tbh. The protocols are not similar enough to be directly interchangeable l.
