ok, so it looks like this project is completely broken and dead. it is a great concept, perhaps there is something in pyramids - i'm just reluctant to move.
You could consider it broken if it is not working with the latest Pylons & related modules. Sorry about that, but I haven't been involved in Pylons dev for a while. And I haven't caught up with the Pyramid developments. I welcome any patches that update it for modern Pylons/Pyramid.
(Update: wasn't supposed to post as anonymous; bitbucket is a bit broken to allow that without warning)
