Today ZBuddah smiled upon me and handed me a small bit of Zen, and I 
came a little bit longer. I was able to make a subclass of Zope2 
PageTemplateFile that overrides pt_getContext and manipulates the 
context into what it should be instead of what Zope2 gives it.

This is a parallell to what ViewPageTemplateFile does in Zope3.


However, ViewPageTemplateFile does one more thing than manipulates the 
context. It also subclasses TrustedAppPT. This makes 
ViewPageTemplateFile *trusted code*. Hohoho, very clever, indeed they 
are file based, and as such trusted. Problem: Zope2 PageTemplateFiles 
are *not* trusted. This means that with my clever hack 
tal:content="view/anything" will fail with "You are not allowed to 
access 'anything' in this context". I tried 
security.declarePublic('anything') but it didn't help!

So close and yet no banana. Any ideas? Is this for some other reason not 
a feasible idea anyway? If I solve this, will I just run into more troubles?
