Live Annotations service is available against Cloud-based Real-time Annotations
The question you asked possibly will not get any helpful answer, as there is no company providing cloud storage real-time annotations without allowing to download the document on your system. I think not yet such technology developed to support the real-time annotations with cloud storage or online based data storage system.
Real-time annotators can annotate the object in the image if they have uninterrupted and high-speed connectivity of Internet and servers where such data have been stored. As on real-time annotations objects can be moving or processed for other needs becomes difficult to annotate on real-time basis and accessing the same image by multiple users can also disturb.
Hence, real-time annotation not seems possible right now, maybe in future such technology get developed and companies will provide the real-time annotation service on cloud-based storage service even without downloading the documents. But right now you get live real-time annotation services that will help you to get the quick annotated images as per your needs.
