Is there a reason why you don't use Chameleon? Since version 1.1 it
should be fully compatible with GAE.

It might be easier to switch to the new kid, instead of trying to make
the highly integrated zope.pagetemplate work for you.

At least Zope2 depends on this engine, so moving the engine out into a
zope.app.* package is not an option, it would have to be some new
zope.* package. I'm not sure what and how BlueBream and Grok use this.

I'd like to hear the reasons for not using Chameleon. To me that looks
like the better forward path and avoid lots of adjustments and a
lengthy migration period for zope.pagetemplate users.
