Possibility to target a composant instance by its id when emitting an event

[pink6440]

Hello,

I was wondering it there was a specific reason to not be able to target a specific composant instance when emitting an event.

why does i need this ?
Targetting a component by its name made all instances be notified of an event ;
Sometimes, i just want to notify the first parent or a specific component instance (when many component of same class are present in the page).

Also, it can avoid many unneccessary XHR requests when an event is emitted.

I had modify the live_controller.js to handle the case of the component name parameter is looking like #componentId but i was wondering if there was a specific reason to not have this feature from the start.
