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

I would like to hear all IO requests in all my web pages, however, when I used the syntax below I only listen to IO with yui example.

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

How can I write a custom method / event or something

My question is actually just below the URL:

I went for a while but there was no practical answer for this, any thanks would be appreciated, thanks.

Try

  (Y.o._map ['Io : 0 '] · Publish new Yio () ({' IO: success': {broadcast: 2}, 'IO: full': {broadcast: 2}, etc.};
