I know this is likely to be wishlist'd, but I wanted to add it to the list. Maybe the framework already exists...?
I would like to be able to send a notification (or, even better, a popup) to everyone on Phabricator from the command line. This notification should NOT be emailed by default, because of the use.
My server is set to an automatic startup/shutdown schedule, for security and energy reasons. It would be amazingly helpful for the system to be able to issue a "the system will shut down in 10 minutes" notification, so people can save their changes, etc. That can only be issued via the command line, obviously, in my case via a Bash script.
This would also be useful for other system-based notifications, such as if an admin needs to notify that the system will be down for an hour for maintenance, etc.
I can imagine that this could probably just live in ./bin/aphlict. If it isn't a massive change, I may be able to do it myself (rusty on the PHP), but I wanted to get clearance and feedback from ya'll first.
