I should have added that it's for an intranet, which probably will never have more than a 100 users (more likely around 30), so security is not a big issue. I would be doing error checking on the input in the php file that receives the html request, so in theory it wouldn't be any less safe than any other AJAX form submission technique I should think.
Still anyone know of a library that works like this? (see my post above)
