If Z4I uses the Zope 2 -> Zope 3 interfaces compatibility package, then 
it's quite different. Let's just put it this way; I don't know anything 
about Z4I beyond the existence of this interface package, which is 
something I didn't like and didn't use in Five. The two technologies 
therefore appear quite distinct..

You can try Five with Zope 2.7 by downloading it, putting Zope X3.0's 
code on the python path, and starting Zope. We've already used Five in 
Zope 2.7, in a Silva, CPS and Plone context. These are complicated Zope 
2 applications, and with Five installed, they remain working as before.
