OpenTeams
Uses Oauth to retrieve email from Gmail but that should be portable enough pull from other sources (seems like there's a stub for Slack? and vestiages of bulk offline email analysis such as large email dumps). Seems to be an evolved version of Immersion

Storing data in music | ETH Zurich
Embedding small data in music, preferably with lots of dominant notes in 9.1-10KHz range, so pop music. Might be useful for data smuggling in the open, if you are within 24m and can stand 400 baud...

Google Duo - The simple video calling app.
Aparently you can now do web Duo from the site if you have a linked Google account for the Duo account. I wonder if this can work well enough to be an alternative to the hangouts web dialer, as an access mode for Google Voice?

Matrix and Riot confirmed as the basis for France’s Secure Instant Messenger app | Matrix.org
Interesting. Apparently french politicians liked Telegram, but russian based was starting to become an issue, so french government decides it needs its own messenger (but not citizens?). Hopefully this means cleaning up the end-to-end encryption more and making the UI easier/safer.
