Honestly, I haven't gotten that far yet. The initial implementation would not incorporate any sort of automatic sync, instead it would be up to the user to tell pipeline to update the data from the server or push new data to the server. When we get to sync, then we will need to probably do some sort of polling if we are using REST and then yes, WebSockets will be something else.
