Do you know if this plays friendly with the jQuery event model?
Looking through the source code, it has its own implementation of "fix" for
events, along with its own data storage for event handlers.
Without testing it, I would tend to think these two libraries wouldn't jam
up and cause a mess.
You implement a jquery-based solution using a pattern like this:
jQuery.fn.bubble = function(type) {
return this.each(function(i){
// Build a fake event, and assign the target==this.
var evt = ....;
evt.target = this;
var el = this;
while (el) {
// Look for a handler of the supplied type.
var handler = ....;
if (handler)
{
handler.apply(parent,[evt]);
break;
}
else
el = el.parentNode;
}
});
};

You're right, it doesn't work.
Maybe NW Events could help here: http://code.google.com/p/nwevents/
It's an event manager and it can fire/propagate 'fake' events.
