How to make Y.io's global events broadcast across instances
===

I would like to listen for all io request in all my web pages, however, when I used the syntax below, I can ONLY listen for the io with the yui instance.

Y.on('io:success', myCallBack);

How can I write a custom method/event or something else to achieve this?

My question is actually the same as below URL:

I googled for a while but did not find a practical answer for this, any help will be appreciated, thanks.
