As mentioned in http://permalink.gmane.org/gmane.comp.gnome.devel.announce/101, libappindicator was rejected for use as an external dependancy for Gnome 3.0. As I understand it, that means that applications supported as a part of the Gnome 3.0 desktop cannot depend on libappindicator for use.
How does this affect Ayatanna going forward? Can libappindicator going to be an optional compile-time component? Is this a sign that the application-indicator framework isn't going to see much adoption upstream, at least as is?
