I've written a similar thing for the Mac, using NSStatusBar [1]. It's no big deal, or reason for a Linux distribution to be "famous". There are zillions of apps in the Mac store that do stuff like that.
Does Linux have a standard API for surfacing interactive icons and menus in the menu bar? An ICCCM extension, perhaps -- set some properties on the root window and cross you fingers? Or would you have to do it differently for every different Linux desktop environment or window manager that supported such a feature?
