AS3 Custom Events

I've read in couple of blogs (this one recently) on the problems with passing data between Objects/Classes. I, myself, used to use Proxy as well as binding data to dynamic classes (ie-MovieClip) a LOT of the time in AS2, but now in AS3 things have changed (for the BETTER!).
In comes Custom Events. I recently used Custom Events in a project where I wrote a Class for controlling the Sound object. I found using Custom Events was MUCH easier than it's reputation is known for, and very similar in nature to Proxy. Below is a quick Sample of the SoundControlEvent.

With CustomEvents it easy to read the passed property without having to access the dispatching object. As outlined below:

var evt:SoundControlEvent = new SoundControlEvent(SoundControlEvent.SOUND_POSITION);
evt.position = _channel.position;
dispatchEvent(evt);

Hopefully Custom Events will become more popular as AS3 gets futher into the mainstream. It makes for easy to read code that extremely portable.
