Since version 3.1, awesome is bundled with naughty, a notification library which allow to raise pop-up in front of the screen to display information you chose. A sort of notification-daemon, but not plugged into D-Bus.

Last days I've began to work on awesome 3.2 (aka the 'next' branch in awesome repository). I've started to chat with Leon Winter on IRC about the possibility to implement notification specifications into awesome.

awesome had since version 3.0 a very light D-Bus support, since it only allowed to evaluate Lua remotely, without getting an answer anyway.

I've hacked it so now there's a D-Bus hook, which is called upon a D-Bus message received. This, plus the possibility to return various data type (not all are implemented as of this day) allowed Leon to enhance the naughty library and to add support for a primary notification support.

I just have to add more D-Bus data type support, and we may be able to support all the specs, with icons support, etc.
