Has the Gnome team thought about working with Mozilla to allow Gnome
to display notifications from their SimplePush API?
http://jbalogh.me/2012/01/30/push-notifications/
https://wiki.mozilla.org/Services/Notifications/Push/API
This would allow websites to send (requested) alerts to Gnome
desktops, even if the alert recipient doesn't use Firefox, or isn't
currently running Firefox.
Or is there some other better way?

I'm not part of the Gnome team, but I think it might be a better idea to
create some a daemon which listens for simple push and then uses dbus to
communicate the notification.
Back of the napkin math looks thusly:
App is installed:
App sends a message to dbus telling the daemon to Register with a PushServer
Daemon receives an Endpoint from the Push server and sends a message via
dbus
App receives an Endpoint from dbus and sends this to the App Server
Message is Received:
Daemon receives the message and extracts the UAID
Daemon sends the message on dbus
DBus routes the message to the app based on the UAIDof the message
App is uninstalled:
App sends a notification to dbus.
Dbus routes the message to the daemon
Daemon unregisters the app
App is garbage collected:
It would be reasonable for the SimplePush daemon to periodically review
which apps have consumed push messages and unregister applications which
haven't been used in a while.
You're right Summers, it would be better for there to be a SimplePush daemon for various OSes, which under Linux would
generate dbus messages that Gnome can display.
By "App" do you mean a desktop application program? Aren't alerts for these working already, such as the new-email
alerts sent by Thunderbird? The new thing here is to allow users to request alerts from websites and have them delivered
to the desktop even if the website is not open, and even if a browser is not open.
Given the existence of a SimplePush service such as the one run by Mozilla, and a SimplePush daemon that listens for
notifications from the service and delivers notifications via dbus, all you need is to give browsers the ability to
register notifications with the service, and give websites the ability to push notifications to the service.
Only Firefox can currently do this, and I'm not sure they'd be willing to run notification servers that can be used by
non-Mozilla browsers and desktops. Perhaps the solution is just to make available dbus daemons for commercial alert
offerings like AlertRocket and XendApp. Or instead some open standard with servers hosted by some giant like Google.

For example: I use irccloud.com to chat on IRC and it sends desktop
notifications. Previously when on OSX, my notifications sidebar would show
me all the new messages and alerts from this website (running inside
Safari).
I think this would be a neat feature to have when combined with the
Messages tray in GNOME 3.
Perhaps, this should have come up as GSoC project idea?
Sindhu, it looks like the alerts built into Webkit-derived browsers like Chrome and Safari -- which is a draft standard
(http://www.w3.org/TR/notifications) -- only gives these browsers the ability to show alerts outside their windows, such
as on the desktop when the browser is minimised. The browser still needs to be running, and unlike SimplePush there's no
mechanisms defined for alerts to be registered, or delivered when the webpage isn't open.
