It's too bad, but 2.7 is in feature freeze, so yes -- HEAD only.  Tests 
would be great!

??? I'm not sure what you mean.  For what it does, I consider it 
feature-complete.  It can handle post-traversal tasks of arbitrary 
complexity.

I currently use it in a site that runs a number of user-based SQL 
queries on almost every request.  Rather than calling the Script that 
performs these queries from every single published object in the site, I 
have an Access Rule:

## Script (Python) "through"
##bind container=container
##parameters=folder, request
##
request.post_traverse(container.preload_customer, ())

For other applications, that "()" could contain all sorts of information 
available during traversal.
