Its dead simple because other services seem to have figured this out. Twitter does actual real time systems, and its not 1-to-1. Slack meanwhile seems to have no trouble delivering me messages. I can confirm these problems. When I had an iPhone and iMessage, they were out of order all the time, and delivered unpredictably. However, Slack, Twitter, etc. are not solving the same problems. iMessage does end-to-end encryption and has perfect forward secrecy (which, if I understand correctly, implies that they need to re-key fairly often). https://www.eff.org/secure-messaging-scorecard https://www.eff.org/secure-messaging-scorecard
