Note that you can make a binary release use an existing python by just changing the start script to point to your chosen Python executable instead of the bundled one.
That wont be quite enough on win32, not sure about other platforms.
The binary release contains extensions that link with the python15.dll They need to be recompiled for 2.0, and will then link with python20.dll
Sorry, I should have been more clear. You can only change the executable to a different executable of the same Python version (unless, as Toby noted, you are willing and able to recompile the Zope C extensions to match your Python version).
