I would be in favor of making the Examples "opt-in" like the Zope tutorial. It seems silly to have it in evey ZODB by default. Make people add it if they want it.
Many, many moons ago I created evan-examples-branch, which allows individual Products to offer sample code without (magically or otherwise) forcing them upon the user. I'd love to see it revived, perhaps as "Examples/Optional Extras" in order to cover the Hurt system as well.
The basic idea is to look for an XML manifest file 'examples/index.xml' in each Product. It probably wouldn't be very hard to use ZConfig instead of XML. Here is the PageTemplates index.xml:
<example name="Assorted Examples">
<description>
This is a set of examples of the use of page templates.
It includes examples of batching, macros, and trees.
</description>
<payload>
<import file="zpt_examples.zexp"/>
</payload>
<view url="zpt_examples"/>
</example><!-- This file can contain any number of examples.
Each one consists of an <example> with a 'name' attribute, containing exactly one <description>. The name and description are displayed in the Examples page. <description> can have a 'format' attribute set to 'plain' (the default), 'stx' (structured text), or 'html'.
An <example> can contain <payload> elements. Each <payload> can contain any number of <import>, <execute>, and <call> elements. These are processed in order when an example is selected from the Examples page. <import> must have a 'file' attribute that names a file in the 'examples' directory to be imported. <execute> must have a 'file' attribute that names a file to be run with execfile. <call> must have a 'path' attribute that gives the path to a Zope object to be called.
An <example> can contain at most one <view> element. The 'url' attribute of a <view> is the URL to view after all <payload> elements have been processed. This URL can be relative to the current folder.
