Why don't you plan to leapfrog 2.11 and go straight to 2.12 (which I
thought you were planning to do anyway)?  That gets you onto a
"supported" version of Python (2.4 is in lockdown), and makes the ZTK
relevant to you.

Plone's policies are in conflict, here:

- - Ultra-stable about the Zope version:  you claim you can't update the
  version of Zope used in a 3.x release from the version used in 3.0.

- - Completely unsupported use of "cherry-picked" updates to the packages
  which shipped with that Zope.

If you can reasonably do the QA to ensure that the second policy doesn't
break Plone, the you can equally well update the Zope / Python versions.
