I'd strongly recommend against trying to make the Zope Interface module 
work directly with Zope 3 technology. I've tried, Zope corp tried, and 
it's rather painful. Five only managed to get off the ground when it was 
decided to use Zope 3 interfaces in parallel to Zope 2's, and basically 
just to ignore Zope 2's.

Five does include Tres' bridge directive that can turn a Zope 2 
interface into a Zope 3 interface from ZCML.
