That's excellent news! Sounds like the service is already paying for itself.
I'm not opposed to video uploads, so long as the video/audio production is decent and the camera isn't in people's faces. I have a Sony video camera with native 4K and optical zoom, with a shotgun microphone attachment for capturing audio in front of the camera instead of the surrounding area. I also have a blue yeti if you want a good microphone for public speakers to use.
We could make this a bit fancier and less intrusive by having a screencast of the speaker's computer to show slideshow material, terminal output, etc, and have an omnidirectional microphone listening and syncing with the screencast.
