Problem

A client might be interested in room information but doesn't need to receieve those updates every delta. Under heavy use deltas could generate to omuch server traffic. For example: udpates of room occupants. A client might only need to update the number of occupants every 10 seconds rather than getting an update sent every time a client joins the room.

Solution

Allow a client to specify how often it should be updated with the update level.

Issues

If there is no update to be sent within the subscribed interval and then the information changes should the client be updated immediately (and the interval reset) or should it just be sent with the next interval.
