I still think it's more natural to pass them in the constructor so that the author doesn't really have to think about tasks while programming, but Notification should support the common EventTarget interface as well.
Then does setting them in the constructor syntactic sugar for

n.onshow = showcallback;


n.addEventListener("show", showcallback, false);

Also, is there no other spec that includes callbacks in the options dictionary?
