I had been thinking that it would be cool if FormEncode validators (or a derivative thereof) could somehow specify JavaScript validation to occur for the field. But, I punted at that for the time. If you want to experiment, have at it! (I concur with Alvin that the AJAX method is a bit heavy-handed for what you'd really want client side validation to do.)
