Is there a way to subscribe to changes on the server (long polling or websockets)?
Not yet, but it is on the road map.
Yeah, that is a MAJOR massive catch.. That pretty much turns this completely unusable for anything other than meaningless apps that that store a users data in a silo. EG, a note keeping app that doesn't have the ability to share notes between users.

, I think you misunderstood. Not being able to synchronize clients in real-time with web sockets doesn't mean there is no shared storage. It's no different than any web app, the backend stores data in a database, so any data can be shared between users.
If I am reading your example above correctly, "value" is synchronous, so it would never know if someone else has incremented it? So reading it client side will be wrong the moment someone else adds it.
The backend is stateless, so in the example, the counter is unique for each user. To share the counter among all users, the backend must save it in a database.
When you execute a remote method on an object, the attributes of the object are automatically transported between the frontend and the backend. So, when you change an attribute in the backend, the change is reflected in the frontend.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.

And again, I ask how the UI gets to know that it has changed.
