Just FYI, in terms of Ajax in Zope 3, we have:

  - KSS (http://kssproject.org), which is what powers AJAX in Plone 3. 
This is designed so that it works in "pure Zope 3". This is a bit 
"different" in that you generally don't write Java Script at all. Take a 
look at the demos on that website to see what I mean. I know Philipp did 
some work with KSS in Grok a while ago.

  - jQuery is being used by z3c.form, apparently.

  - Some things in the z3c.widgets package uses Prototype. Note sure how 
widely used they are, though.

The problem with JS solutions is that you can't just pick and choose for 
different applications. Using more than one AJAX library simultaneously 
sometimes leads to conflicts, quite likely causes inconsistent 
UI/look-and-feel and almost certainly bloats the page download size and 
increases page load time.

There was a huge debate prior to Plone 3, about a year ago, about 
whether to use KSS (which we went with in the end) or Bling (which is 
just a way of using Prototype in page templates). I really don't want to 
have that debate again, but it's important to pick carefully.
