I don't have any Chrome plans (I work for Mozilla), but I've heard rumors that the Chrome team is working on their own push notifications.

Eventually I want to get these APIs standardized and in other browsers, not just Firefox and Boot to Gecko.

Will this land (eventually) in XULRunner as well ?

Yes, it'll be part of the Gecko platform.
