I feel it's ridiculous to track changes to fields BEFORE the complete data set (form) is submitted, unless that is a specific intention of the business logic, which I don't think in this case it is. Just because AJAX can do all that "cool" stuff doesn't mean it should be shoehorned into every application orifice possible. And... AJAX IS a display technology. Is JavaScript and XML doing the backend work? It's merely a conduit to and from the backend, not the backend itself.
