It'd be fascinating
It'd be fascinating to work out how any given fragile slurpy service gains such take up considering how widely its fragility and slurpiness are publicised.
Video conferencing software biz Zoom has bought Keybase in a surprise move just weeks after hiring Facebook's one-time CSO. "There are end-to-end encrypted communications platforms. There are communications platforms with easily deployable security. There are enterprise-scale communications platforms. We believe that no …
There are end-to-end encrypted communications platforms. There are communications platforms with easily deployable security. There are enterprise-scale communications platforms. We believe that no current platform offers all of these. This is what Zoom plans to build
So how do you do that without the N^2 problem? I believe these multi-picture conference services do the video mixing in the central server to avoid that problem & make the video data feed to each participant just one picture. That requires the server to see the video (and audio), ergo no end-to-end security.
Trying to do it in each client would be 'interesting'.
Yes, it's probably a necessary PR thing.
PS Unicode superscript 2 (² in html) doesn't work.
Zoom, Teams and WebEx all demonstrably send all the individual video streams to each participant.
You can tell because a) each participant sees the others but not themselves and b) they allow you to rearrange the local layout.
It's actually far easier this way, as the central server simply bounces the streams on to the other participants.
Gracefully degradation is easiest handled by just dropping packets, and slightly better by telling the sources to reduce their bitrates when not "active".
All of this and more is well known.
Yes, the *really* big conferences pre-mix, but in their own machine, not a remote central server. Then broadcast that, eg via Twitch.
Security guru Bruce Schneier recently blogged that he likes Zoom and that they have fixed the most egregious recently disclosed security flaws. He also mentioned that they have some ways to go with key management and with security for the free app, and that the web version remains unencrypted. But he still uses it, even for corporate business. And he likes the feature set.
Love the name. Ironically the same issue exists on other platforms, not just zoom... but it's not sexy to call it what it is: using a random number generator get the meeting numbers.
Zoom has had features to block this in the admin portal for a long time. If you want to use a name for it call it "stupid user bombing".
