DBus signal to disable reminders/notifications

[David Faure]

Hello,

Is there some spec that would allow to implement a desktop-wide signal in 
order to disable things like calendar reminders, chat notifications, new email 
notifications etc. during a presentation?

Calligra Stage, LibreOffice Impress and other presentation software could emit 
a dbus signal when starting/stopping a presentation, and calendar/email 
software would listen to that and disable/enable reminders/notifications.

I give professional trainings and give talks at conferences, and it's annoying 
or even embarrassing when (recurring) calendar reminders pop up.
Imagine if one said "It's time to take one of those anti-baldness pills" :-)
