Droppable Behaviors in Etoys

I am looking to create droppable behaviors similar to those in Lively Kernal.  I can do it with connectors like this:

script1
self getDestinationPlayer setColor: self getSourcePlayer getColor

But would like to simply drop a morph onto another morph to accomplish the task.  How can I get a list of morphs my "droppable behavior" is overlapping?

Extra points for a sample project :)

Thanks,
Stephen

You can use Morph>>morphAt:behind:unlocked: method to get a list of morphs 
that lie below a morph at the given position.

The embed menu op uses this to extract a list of morphs. See 
Morph>>potentialEmbeddingTargets and its callers for examples.
