I found this old class. This was one of the first things I ever made with MooTools (and JavaScript.) It's surprisingly not completely horrible :)
http://jsfiddle.net/rpflorence/cn8a2/ It posts the form with JSON, then if it finds an 'error' key in the json it runs through that to find all the elements with errors and provides a message. Otherwise fires a validate event.
