Any way of doing that would be something of a major change in the way your application is written. Instead, have you considered caching that update? If you do it carefully (and maybe work in some sort of diff function so that a client can only retrieve changes from the previous update) you shouldn't have problems unless you have many thousands of clients on your network.
