I published a minimal zope3 app on app engine, along the lines of what of my post from yesterday. you can check it out at http://zope3.appspot.com
its basically a minimal zope3 application, using a custom publication, and bootstraping some components via zcml.
also a simple test runner for verifying packages on the google app engine

the minimal egg working set used by the app.

several modifications to the eggs were nesc to remove security.proxy references, and remove some BBB/deprecated code.
This set of eggs, just fits in under the 1000 file limit ( after manually removing extra locales in zope.i18n and pytz, its about 980 ). we could slim the eggs down a bit, ditch the docs and the tests for a minimal egg, and maybe have a ceiling of 200-300 to play with. but clearly for most zope/grok applications, which will be using a quite a bit more eggs, zip based imports are probably the only realistic option.
Loading zope is about a half-second, but once its initialized, subsequent executions run fast, from a timer around the import statements,
Initial Request Zope Load Time -0.588495016098 Subsequent Request Zope Load Time -0.000102996826172
in terms of exploring zip based imports, the suggestion guido pointed out in GAE issue 161, was using something like importlib/zipimport to manually load zip archives/eggs, for another day.
