Cloud watch state and across shared libraries

I see all of the options to put the content in the cloud. I don’t really like that idea. I would like to see watch state synced to the cloud. I have setup my server and it would have been to had that be in the cloud for when i signed in. Another piece to that would be when accessing shared libraries. If it is something that I have already watched from my library then can the same show be marked as watched in other libraries?
