Interesting, could you shed some light on the tech behind this? For example, does this use a custom solution to display notifications or Growl / ML notifications?

On Mountain Lion, we use the Notification Centre by default although you can opt to use Growl if you would prefer. In Lion, only Growl is available (obviously) :)

And are you poling the noti server? I'm wondering how realtime it is :-)

[adamcooke]

We use a socket-based connection on the clients. Messages should be delivered in very near to real-time. There's no polling here ;)

is this mac only?
