Thank you, David, for the elaborate explanation. Just for curiosity's sake, can you explain why desktop notification work with Web browsers and the Ubuntu desktop, without any server-side control from our side? (e.g web.skype.com will show an OSD for incoming messages)
Is this all just because the browser tab is contiuously polled for changes? It's not websockets that plays their part, is it? Is an OSD desktop notification of a website eqivalent to a WebApp always being active? So, the WebApp would show an integrated platform notification of Ubuntu Touch?

And I think the converged desktop will benefit from that evolution by not taking it for granted that the application is always on and always connected.
