Here's a copy of a drop event listener I just pulled from some old
DynaCore code (now there's a blast from the past):
myDrop.ondrop=function(e) {
me=e.getTarget()
source=DynAPI.document.dragobject
me.addChild(source)
}
The listener is then attached to the required dropzone.
However, if you look into how to implement "simple" events, you could
attach the above method to the DynLayer.prototype and you will end up
with a method that is used across ALL dynlayers.

It is possible to attach the same EventListener to more than one layer.
Look into this to see how to implement your desired setup.

You should check out ww.dynacore.net
Pascal has done some amazing this with the DynAPI and DHTML in general.
