yes. only if it is free. only if it is free. yes, but only because gpl
allows for gpl code linking with the major components of the os even if
they are proprietary.

err, no. if you write an external module using only python code, as long
as you use a gpl-compatible python to run zope, you can call your
external code from zope. if you write a product suclassing dc code,
you're effectively 'linking' and gpl limitations apply.
