Joe Walker and I have recently completed an article "Ajax and your CMS" for CMSWatch on how Ajax could impact Content Management systems. We identify two main aspects - Ajax in the CMS interface and Support for Ajax-driven web sites. We consider the benefits and potential drawbacks. Thanks go to Tony Byrne for his input on the article and to Day and Mediasurface for their assistance with the vendor specific research.
Out of the box thinking... out of the box.
