Evan, Once again, I have answered my own question. From the GNU website FAQ: What does it mean to say a license is "compatible with the GPL". It means that the other license and the GNU GPL are compatible; you can combine code released under the other license with code released under the GNU GPL in one larger program. The GPL permits such a combination provided it is released under the GNU GPL. The other license is compatible with the GPL if it permits this too. So, any combination of GPL and non-GPL code must be released (published) under the GPL. The ZPL is 'compatible' because it does not prohibit adding the GPL to code originally covered under the ZPL.

Everyone seems to disagree but it looks like I cant use GPL'd Products without GPL'ing the entire zope installation. Anyone care to dispute this?
I certainly will. The GPL doesn't kick in unless you are *distributing* the GPLed code, and using it to run a website doesn't count as distribution. You can *use* GPL'd Products with Zope, Apache, or even totally closed binaries.
Of course, if you *are* planning on packaging up GPL'd code with Zope or other code and selling/giving the combination away, you do need to be sure all of the licences are compatible (Zope 2.5+'s ZPL 2.0 licence is officially GPL-compatible).
