On Particletree.com today, there's a new post from Kevin Hale with a pretty good roundup of AJAX toolkits.

This is a pretty decent collection, but in no way a definitive list of Ajax elves to get you from refresh zero to remote scripting king.

Items on the list include: SAXJAX, AjaxAC, CAKE, Ajax Wrapper, and even a ColdFusion implementation - CFAjax.

Thanks to PHP Magazine for the pointer...
