Adding an interface to provide a list of listeners

Hi!

At a recent W3C PFWG meeting, the group (again) lamented the lack of a
standard way to get a list of all the Event listeners (of a specific type,
at a specific element, etc) in the DOM.

We are happy to put together a proposal about this, with use cases, but we
are not sure if we should target this at the DOM itself or at the DOM
Events specification.

Obviously we are not looking to rock the boat here w.r.t DOM4 or anything.
 We are just trying to figure out who we should be talking to about getting
this included in some future specification.

Suggestions?
