Shouldn't it be focused on compatability with the ZPL instead of the GPL? From what I hear, there still are issues with, for example, distributing Python Products as GPL with Zope.

Anyone with better knowledge about this care to enlighten me?

See an earlier post on a different thread. Chris wrote that the license is BSDish and is therefore compatible with ZPL. This means that mxDateTime could be distributed with Zope.
