I was thinking if we imagine the agent is able to behave like a drag-drop destination, then the agent could signal a drag started, the client would accept the drop, and only then the proposed xfer messages would come: server sends xfer_start, etc... There are missing messages to have the agent&client behaving like a drag-drop destination.
