 * **signal-cli-rest-api** - no gui, need a sim card phone number registred,
-  worse concept for sending notification to multiple users,
-  where you need to manually set everyone who should receive,
-  as oppose to having a "room/topic" to which one can "susbscribe",
-  but if signal is widespread enough and you are not asking people to install
-  another app then its a winner
