Actually a pretty good question ... I was under assumption that you  
could call Event.observers in Prototype and get back an array of  
element and handlers but after glimpsing through the API was not the  
case.  In fact since it's not a DOM-level call it seems that it would  
be pretty API independent.  It seems that they even removed that and  
implemented a stacked cache a while back ...

http://dev.rubyonrails.org/browser/spinoffs/prototype/trunk/src/event.js

Interesting that you can't get back an array of listeners for an  
element.
