right.

not only. i can assure you that somebody in debian find even a single
line of gpl code in the zope main packge zope will be removed from the
distribution until license compatibility is (re)estabilished. same story
for zope products currently available in debian. i don't have all that
time, so i wont be the guy doing that, but, first or later, someone will
surely try to track down all the licens incompatibilities in zope debian
packages. just look at the kde/qt problem (now fortunately resolved...)

right. maybe dc has some to gain froma gpl-compatible zope and not only
the no-harm i detailed before.
