*hack hack*

Put this in your Extensions folder, under whatever filename you see
fit:

def tpd_last_editor(self):
    """Return the last editor of an object."""

    jar=self._p_jar
    oid=self._p_oid
    if jar is None or oid is None: return None
    return jar.db().history(oid)[0]['user_name']


Then, create an External Method to access it.

Good enough for me.  With this applied it's now a method of nearly any
Zope object.  (In case you're wondering, tpd are my employer's initials;
I figured it'll prevent a namespace collision.)

Zope Developers, feel free to do whatever you want with it.  I recommend
making a part of the standard API.
