Drag and drop unfortunately won't work due to limitations in the NPAPI. All plugins run in their own process. What you are seeing in the applet area is actually an image of what the applet process has rendered. This also means that any event that is intended for the applet has to be serialized and sent to the plugin process. This works well for mouse, key and window activation events but no provision was made for drag-type events, so there's no way to know what was dragged onto the applet.

This will require changes from all of the browsers, so I'm not optimistic it will ever happen.
