receiving messages inside a javascript object

Hi.

If you have multiple javascript "views" (like in model/view) of something in
Max, you will want them to be notified when the model changes, so that they
can refresh, for example. So it would be useful to bind a javascript
function to a max name so that the function gets called on every messages
that is sent to that name. It is the complement of messnamed().
Is there another way to have the same result at the moment, without using an
external [r] object?
Is there any chance to have such a thing in a future version of [js]?

Thanks,

Maurizio.
