Just to enhance a bit the comments here, all the implementations
guides I've seen about drag-and-drop very quickly rely on the fact
that a state is assigned with the drag-operations-sequence, e.g. to
define acceptance or rejection and that this state is unique globally
on the whole user-interface.
Much of the behaviours of many GUIs change while a drop is happening,
Apple's exposé is another such: you can trigger it while dragging.
I am sympathetic to timeless's wishes but I have the impression
they're not really realistic, I don't see normal mobile phone user
able to copy-and-paste instead of drag-and-drop with a cursor if the
page developer has not also thought of enabling copy-and-paste...
