The Zimbra Ajax Toolkit :

Zimbra is contributing to the Open Ajax Initiative by providing open access to the Zimbra Ajax Toolkit (AjaxTK).

Zimbra has used AjaxTK to push the envelope of what we think of as a Web page by developing a complete online Collaboration Suite, including enterprise-class e-mail, calendar, and contacts.

The AjaxTK squeezes the responsiveness gap between a Web-based application and a standard desktop-based application to near zero.

The Dojo Ajax Toolkit :

Is a runtime tool which will be supported in Eclipse's Ajax Toolkit Framework (ATF).

Dojo is a community project designed to unify the efforts of the JavaScript and Dynamic Hypertext Markup Language (DHTML) communities in a single direction by building a standard JavaScript library.

The community realized it wouldn't get far without people working together, so three separate predecessor tool kits were unified to form the Dojo Foundation, which owns and maintains the code. Dojo has several optional packages, including an Ajax edition; an I/O edition; and a "Kitchen Sink" edition, which includes the entire tool set.
