I've done some work towards this, but never had a big-enough chunk of time to get it finished. There's a simple mock-up available of how the classnames, CSS and JS would interact - available here: http://www.formfu.org/tmp/client-side-constraint.html I've not checked-in the work I've done on this, and would need to take a look at it, to see if it's still any use. Would you be interested in trying to get it working, based on that mock-up? I'm not really likely to have the time to work on it in the next couple months, at least.
