[Grok-dev] Grok with existing SQLAlchemy mapped classes

I have an existing Web application written in Python that I'm looking to
re-implement in a modern Python framework. Now that Grok is approaching 1.0,
I am taking another look at it for this purpose, and it's lookin' good.
My only question (at this point, anyway) is whether there is a way to reuse
existing SQLAlchemy-based model classes without having to add any Grok
directives and/or Zope-specific integration code to them. The model for my
application is in a "core" package that *cannot* be modified to support Grok
(or any other Web framework) directly. One idea I have is a function that
takes a SA mapped class and returns a Grok model.
I've started looking at some of the libraries for integrating SA with
Zope/Grok, but I admit that I haven't looked very deeply as yet. I've also
been reading the Grok docs and this list but haven't found a definite answer
yet. Is what I want to do already possible? Would it be straightforward to
implement something like an `sa_model_wrapper`? Can I create a subclass of a
SA model class that uses `grok.Model` as a mixin?
Any pointers or suggestions would be appreciated, and if RTFM if part of the
answer, please give a page number. ;)

days ago and nothing happened. Now I've subscribed through the mailman UI
and am sending this directly to the list address.]
