That's great! Note that you will either need Zope 2.10 or Zope 2.9 + 
Five 1.4 for this.

The latter.

Short answer: package namespaces.

Long answer: Say you're creating a widget library. You could call your 
package simply "widget". But then if I create a widget library and 
called it "widget", too, we'd have a conflict and couldn't use them at 
the same time. That's why you call your package "george.widget" and I'll 
call my package "philikon.widget". Makes sense?
