I'm not sure about the entire history of the license, but it looks to have been chosen when the project originally was hosted on the zope.org community site.
As the project as grown, I think its time to update the license to one that provides thesame rights and protections but its more commonly knownBSD 3-clause

As very minimum I would like to update the license from the currentzope 2.0 to its more friendly written revisionzope 2.1

The license proposed is MIT License.
