True, you did, it's just that you connected these topics particularly 
with refactoring legacy code, while I've been thinking more about them 
in the context of new code.

The sketchy implementation is here:

http://svn.zope.org/grokapps/rdbexample/

(the declarative-directives branch is the only one that currently 
actually "works", by the way).

In particular the interesting bits are in the sub-package 'megrok.rdb'.

We're hoping to convert this code to use zope.sqlalchemy, and also start 
implementing some of the configuration details we discussed in another 
thread. Right now we're focusing on making this work for Grok, but you 
know we have the habit of splitting off more commonly useful code over 
time, and external contributions can of course accelerate that work. :)
